The General Catalogue of 6188 stars herein contained is the result of an attempt to deduce for those stars the most accurate positions and motions that are readily attainable from the means at command. Computation of the motions has been the primary aim of this work. Putting the results in the form of a star- catalogue for the epoch 1900 is a natural method of exhibiting these results and is, apparently, the most useful way in which they' could have been presented ; but it has not been at any time the first consideration. The accuracy attained, while governed in the first line by the supply of good observations that have hitherto been made upon these stars, in a very important degree has also been limited by practical considerations as to the amount of com- puting that has been available. The liberal support of this work by the Carnegie Institution has somewhat modified this point of view, so that the question has vir- tually been : what amount of computing can be wisely and economically devoted to this object how much is it worth while to expend ? The computations for this catalogue are intended to be practically exhaustive (so far as these stars are concerned) of the meridian-observations of precision which have been made from the time of Bradley to the present and that have been col- lected in star-catalogues of comparatively superior accuracy or extent. Such zone- observations as those of Lalande, Bessel, Argelander, Lamont, and others, were omitted from the computations as lacking in the precision requisite for the present purpose. There were also excluded many series of observations (mostly found in periodical publications) that contain only a small number of stars partly because of the small return in proportion to the labor involved in the use of such catalogues, and more particularly because of the difficulty of ascertaining the systematic cor- rections that such catalogues may require. Strictly zodiacal catalogues were not included in the computations because, among other reasons, even without them, the motions of the stars within the zodiacal region can usually be determined with greater precision than those of similar classes of stars without that region because many of the star-catalogues of earlier dates are more complete in the neighborhood of the zodiac. A list of the catalogues of observation employed in the construction of this work is given later in this Introduction. Many years have passed since there has been available for the use of astron- omers a general catalogue of stars founded upon the combined results of all the principal catalogues of observation. Heretofore the General Catalogue of 8377 Stars by Francis Baily, published by the British Association for the Advancement of Science in 1845, nas constituted the first and last attempt of this kind to col- late the results of meridian-observations upon the stars in a large and compre- hensive way. Evidently designed to facilitate the progress of meridian-astronomy in practical ways, it speedily came into general use as a work of reference of very great utility. It was probably not designed by its author as a basis of further investi- II PRELIMINARY GENERAL CATALOGUE OF STARS FOR IQOO gation in any critical problem requiring the most accurate available values either of the positions or motions of the stars. The records of observation then were too scanty to afford much hope that the best values of proper-motion which could be computed for the generality of stars at that time would have been very much better than rough approximations, or otherwise than very unsafe for the purpose of pre- diction. Practical considerations seemed to be opposed to any very great refine- ment in such computations; and accordingly no such refinement appears to have been attempted in the construction of the Catalogue of the British Association. Furthermore, owing to the amount of reliance placed upon the precision of star positions obtained from Lacaille's zones (1750) and upon Taylor's earlier results at Madras (which contained very anomalous errors in declination) the proper- motions of the far southern stars printed in the "B. A. C." are wholly unreliable. In the first years after its publication the B. A. C. was doubtless used to a considerable extent for predicting positions of the stars to be used in problems of precision ; but in the course of time it must have been distinctly seen that this use of the Catalogue was no longer justified. Yet the use and appreciation of that work scarcely waned during the first quarter of a century after its publication ; and on many points it is consulted with advantage even yet. It seems worth while to have recalled these facts about a notable work in the history of astronomy, in order to throw into proper relief the remarkable fact that more than sixty years have elapsed since the publication of the B. A. C. without the appearance of a work, or combination of works, to take the place it once held. The construction of such a catalogue has been suggested from time to time in a tentative way, but seems always to have been regarded without definite encourage- ment. Apparently two ideas have operated effectively as the chief obstacles in carrying out the preparation of an extensive general catalogue of stars. The first has been that, pending the completion of certain works of meridian-observation, the time has not been ripe for the production of such a work. The second is analo- gous to this, viz. : that a general catalogue aiming to exhaust the existing material of observation upon the brighter stars (4,000 to 20,000 in number, say) would be almost necessarily out of date soon after its publication. Very quickly the need for a new edition would be felt, owing to rapid accumulation of further meridian- observations. But these objections, whatever force they may have against the construction of a star-catalogue chiefly for the sake of the star-positions it contains, would have far less force against the general computation of proper-motions. From time to time these are needed and must be had in various departments of astronomical research, and especially for the study of general stellar problems in a variety of forms. Therefore, the question whether it is worth while to construct a general catalogue of the principal stars becomes a question whether we shall incur the proportionally small additional labor and expense involved in putting general computation for proper- motions into the form of a published catalogue, after the main portion of the required computations has been effected for another purpose, of conceded utility. Perhaps the answer to a question like this can best be referred to the test of future experience. At any rate, it has seemed to the author that a great variety of uses would be subserved by the publication of such a catalogue. INTRODUCTION III SCOPE OF THE CATALOGUE. This Preliminary General Catalogue contains the computed positions and the motions, for the epoch 1900, of 6188 stars that are regarded as specially important. That the stars ordinarily visible to the naked eye are of special interest would probably be generally admitted without serious protest, not only because that is the class of stars which most attracts attention and with which we are best ac- quainted, but also because it is extremely probable that these stars are in general among our nearer neighbors. On the whole they have been more frequently and accurately observed in the past than any of the fainter classes of stars. The present Catalogue contains about 4030 stars rated upon the natural, or historic, scale herein adopted as of the sixth magnitude, or brighter. Of these the count shows 1919 in the Northern and 2111 in the Southern hemisphere. These numbers are approximate only, since they are somewhat dependent upon the treatment of double stars ; and because they are still more dependent on the uncertainties in determining the brightness of the stars. Of the remaining 2158 stars all fainter than sixth magnitude a few are included because of their proximity to brighter stars; others because they were observed by Bradley (though a very few Bradley-stars have been omitted); and still others because they are among the stars whose positions, though not observed by Bradley, were determined with a considerable degree of accuracy previous to 1850. For all these stars it was possible to determine their motions with greater accuracy than that which attaches to the generality of faint stars not included in this Catalogue. Therefore, these stars are especially interesting for two reasons among others: First, on account of the relative accuracy of their computed motion, present and prospective, they afford suitable material from which to secure enlargement of the existing lists of standard stars; secondly, these, together with the great majority of the stars visible to the naked eye, furnish the best available means for critical tests upon certain points that may come into consideration relative to systematic motions of the stars. HISTORY AND DESIGN OF THIS WORK. Perhaps the easiest way to describe the place in the line of sidereal research which this work is designed to fill, as well as to indicate the ideas and purposes upon which it is founded, is to note in a cursory way successive steps in its evolution. Many years ago a plan was formed at the Dudley Observatory for a critical discussion of the motions of all stars to which have been attributed, with reasonable probability, motions as great as 10" per century. The work progressed very slowly at first, in the intervals of other employments ; but as it proceeded the conviction grew that the problems for which we need a knowledge of stellar motions require comprehensive (not fragmentary) treatment, if a given, large amount of labor is to be expended to the best advantage. Thus, it is even more important that stellar motions shall be free from systematic errors than that they shall be merely precise in the differential sense. But if that be so, the most responsible part of a work IV PRELIMINARY GENERAL CATALOGUE OF STARS FOR 1 900 aiming to compute accurate values of proper-motions for a very large number of stars might be the ascertainment of the systematic corrections required by the various star-catalogues. This will readily appear upon consultation of the Tables of Systematic Corrections, in Appendix III of this volume. This correction is especially marked for Bradley's declinations, hitherto a very important element in the derivation of proper- motions. For large areas of sky south of + 40 of dec- lination, centennial proper- motions in declination computed by means of uncorrected declinations of Bradley-Auwers compared with perfect declinations 100 years later would systematically differ from the corresponding quantities printed in the present work by i'/5, or more ; and in the zone + 34 to + 38 by 2" or more. While this may be an extreme illustration it serves to indicate the nature of possible effects due to the application of systematic corrections to the positions contained in the catalogues. It becomes obvious that when we are dealing with the smaller proper-motions the elucidation of the amount and direction of residual-stardrift in various parts of the sky may be dependent upon the systematic errors of the star-catalogue in a very important degree. Governed by these and other consider- ations, the author decided to alter the original plan of reluctantly confining his attention to stars having only comparatively large proper-motions, and, as the indispensable preliminary to his work, to institute a thorough inquiry as to the systematic corrections required by the various catalogues of observation in order to make each so far as possible systematically conformable with the combined result from all. It is not necessary here to trace the various steps in these operations. It is sufficient to say that the plan involved the preparation of an extensive catalogue of standard stars. The close of an important stage of this work was marked by the publication of the Catalogue 0/627 Principal Standard Stars, together with various chapters explaining the methods employed in the construction of that catalogue and exhibiting, also, the systematic corrections required by the various star-catalogues in order to bring them into conformity with this new system. (Ast. Jour., Vol. XXIII.) These articles were also reprinted in a separate publication entitled, "Catalogue of 627 Principal Standard Stars." The systematic corrections there published have since been subjected to thorough revision on the basis of a greatly extended list of gwaw'-standard stars; but, fundamentally, there has been no sensible alteration of the general system. From the beginning of this work it had been assumed to be quite as important that we should know the motions of stars in the Southern hemisphere as in the North- ern. It would, therefore, be important for ascertaining systematic corrections not only that there should be formed a new and very extensive catalogue of standard stars, distributed over the entire sky from pole to pole, but also that the positions should form a consistent and homogeneous system derived from careful considera- tion of all suitable observations southern as well as northern. This catalogue would have to be extensive, because it would be impossible to ascertain properly the systematic corrections required for the larger catalogues like Arm 40, Radcl 45, Bruss 65, Cord 75, Cape 80, etc. without a much larger number of comparisons with standard stars than had been available with the existing catalogues INTRODUCTION V of standard stars. In order to facilitate the selection of these stars it was apparent that the safest and most economical plan would be to form a card-catalogue of all the stars contained in what may be termed catalogues of precision of a date of observation earlier than the middle of the nineteenth century. Those stars contained in a large number of these earlier catalogues would be more useful than others for ascertaining the systematic corrections of these same catalogues, both because of the frequency of their use and also, since the motions of such stars can be more precisely computed, they make better standards. This course, once adopted, rapidly led to extensions of the original plan. After the older catalogues of observation had been drawn off upon the cards (except fainter stars of Groomb 10 and Radcl 45), including all the important ones of an observation-date earlier than 1855, the original intention had been not to include the later catalogues entire, but to transcribe only for stars found in the earlier catalogues. But it now seemed that the inclusion of all stars down to the seventh magnitude, though it would much increase the labor of transcription for the remaining catalogues, might later prove to be very desirable in view of the development of our plans then going on; and that the collection so formed would, in any case, constitute an asset of value. This extension of the list was effected slowly and rather imperfectly at first, but subsequently was improved. In its present state the card-catalogue contains about 25,000 stars. There are included all that are noted in the Bonn Durchmuslerung, Potsdam Photometry, Harvard Photometry, or the Uranometria Argentina as of the magnitude 7^0 or brighter. The inclusion in our list of stars down to the seventh magnitude, in addition to all stars occurring in certain catalogues of precision of the first half of the nineteenth century, was primarily due to the desire of selecting stars upon some simple criterion which should give promise at the same time that the stars so selected would be : 1. On the whole, nearer our system than the stars not included. 2. As a rule, better observed than the others. 3. For certain technical reasons, not chosen with reference to the amount of proper-motion any particular star may have. In this collection was presented an almost irresistible temptation to ascertain, so far as possible, the motion of each star therein, and eventually to produce an extensive general catalogue of the positions and motions of these 25,000 stars. Meanwhile we were at work upon the "Catalogue of 627 Principal Standard Stars" already mentioned, and upon its subsequent extensions, resulting for the time being in computed positions and motions for about 2500 so-called Standard Stars. About that time, in 1903, the Carnegie Institution of Washington had come to the aid of this work ; and three years later had so far increased its interest as to develop this project into its Department of Meridian Astrometry, with liberal appropriations for carrying out the construction of the proposed large general catalogue (including about 25,000 stars) to which allusion has already been made. To complete this extensive work, including heavy tasks in meridian-observation as planned, would evidently be the labor of many years. The question naturally came up whether it would be necessary to defer the publication of all catalogue- VI PRELIMINARY GENERAL CATALOGUE OF STARS FOR 1 900 results until the completion of the entire work, so far as now definitely planned. It seemed to the author that, generally speaking, the work ought to be so planned that parts of it which may be useful in the progress of science could be published with advantage whenever such results in a well-defined field have been attained in the current computations, even though these partial results might be swallowed up later in the final results. Meanwhile, the desire to provide the means for present utilization of some of the smaller and less precise star-catalogues, as well as of the Gesellschaft-zoms, through the ascertainment of their systematic errors, had brought about the increase of the so-called standard catalogue to nearly 4000 numbers. It then appeared that to increase this list still further, to include especially all stars of the sixth magnitude or brighter, would add, proportionally, no excessive amount of labor. Thus the resolution was somewhat suddenly formed to present for publication, at an early date, this General Catalogue, preliminary to the much more extensive one that is contemplated as among the favorable probabilities. These results might have been held back to await completion of the larger work, but this course would have entailed delay in making generally available what are believed to be useful results. Thus the preparation of this work for publication at once is not so much the result of an original deliberate plan as it is the consequence of an evolution in the progress of these investigations. In addition to acknowledgments for assistance in the preparation of this Catalogue furnished by Dr. Seth C. Chandler, and by the directors (and other astronomers) of various observatories, mentioned at appropriate places in these pages, my thanks are due to the corps of assistants and computers who have labored so zealously upon this work. Mr. Arthur J. Roy, chief assistant, has been of very great service in all departments of the work, and particularly in applying the checks and scrutiny necessary for the avoidance of errors in the final work. For this duty he has an unusual aptitude; and if the results of computation as they appear in the final manuscript should prove to be unusually free from mistakes, this will be due as much to the skill and diligence of Mr. Roy as to my own efforts. Mr. Varnum, besides other responsible work, took charge of the solution of equations of condition employed in deduction of the positions and annual variations of the stars. Miss Beulah Benway is also deserving of special recognition for the great extent and accuracy of her work upon the more responsible parts of the computations. In fact, all the members of the staff of assistants and computers labored with the zeal and industry betokened by a personal interest in the work. The reading of proof-sheets for the Catalogue itself was carried through, during my absence from the country, under charge of Mr. Benjamin Boss, Secretary of the Dudley Observatory. INTRODUCTION VII DESCRIPTION OF THE CATALOGUE. A few words more specifically descriptive of the contents of the Catalogue and explanatory of certain points in its scope, construction, and use may now be in order. First, let us consider the material of observation actually included in its construction. Search was made in every published catalogue of the following list for positions of stars contained in this Preliminary General Catalogue. It does not seem necessary to give the full title in each case, but only enough to make the identification clear.

As a rule, observations which exist only in the form of annual catalogues, like the Radcliffe observations following Radcl 60, the Cambridge observations fol- lowing Camb 30, and some others, were not employed in the present computations. An exception to this practice exists in the case of declinations of the principal standard stars contained in the author's former work, Declinations of 500 Stars; for these the authorities therein given were also employed as they had been pre- pared in the manuscript of that work. Nor was it considered advisable to make any special effort to secure all the results of available catalogues which may now be existing in manuscript at the respective observatories. Yet some requests for such material have been made from here in several instances, and have met with most generous response, as indicated in the following list : Berl oo.

X PRELIMINARY GENERAL CATALOGUE OF STARS FOR 1900 Bonn oo. Extensive extracts from the new general catalogue, in manuscript, of Kustner's observa- tions at Bonn, +0 to +54. The partial catalogues were published in Nos. 4, 5, and 6 of Veroffentlichen der Kon. St. zu Bonn. However, when these extracts were received the printer's sheets of this Catalogue were substantially complete as to the positions and motions of the stars; but a careful comparison of P.G.C.-Bonn oo was made and the results will be found in the table of systematic corrections, Appendix III. Cape 06. Catalogue of 1390 stars of which 1150 are south of 36, in manuscript, from Sir David Gill, Astronomer Royal at the Cape. These results, derived from observations made at the author's request, were completed within one year from beginning of the observations and communicated to the Dudley Observatory within a few weeks after the termination of the observations. There were in general three observations of each star, occasionally more. With Cape oo they constitute a complete reobservation of the stars in this Preliminary General Catalogue south of 36. Other manuscript contributions and advance printers' sheets were sent to the Dudley Observatory in aid of these computations by the directors of the Paris, Cape, Edinburgh, and Greenwich observatories, and by Professor Porter of the Cincinnati observatory, which subsequently were superseded by the published catalogues. The later epochs of this Catalogue have been also strengthened by observations made at the Dudley Observatory that are not yet published. Every star of the Catalogue between 21 and 37 (as well as some others) has received at least two observations by the author with the meridian-circle of the Dudley Observatory at a mean date of about 1898. Nearly all stars of this Catalogue between +1 and 2 were observed twice near the epoch, 1900, by Mr. Arthur J. Roy, first assistant of the Dudley Observatory. Between 700 and 800 of the stars north of 20 that were most in need of special observation were observed here four times, or more, in the years 1905-1906. These stars may often be recognized by the large p. e. of 100 fi, and the comparative lateness of the epoch. They are mostly between the fifth and sixth magnitudes. In a very few instances of stars between the fifth and sixth magnitudes that are extremely deficient in earlier observations, the Histoire Ctleste of Lalande, Rumker's catalogues for 1836 and 1850, Argelander's observations published in Vol. VI of Bonn Observations, and some other authorities of comparatively feeble weight, were included in the computations, with rough estimates of the systematic corrections and weights. INTRODUCTION XI THE STANDARD CATALOGUE. Primarily the standard catalogue contained within this General Catalogue has been prepared for use in this investigation. It is designed to serve any other pur- pose where high precision is required. In the present investigation the standard catalogue and the systematic corrections were involved together, virtually as the solution by successive approximations of equations containing a large number of unknown quantities. The problem was to make the sums of squares of the devia- tions of the several component star-catalogues at various epochs from the standard a minimum. The effect should be, that when a catalogue of observation, by the application of systematic corrections to it, has been brought into close general con- formity to the standard, it represents the latter at that epoch, and for that epoch extends the latter to stars not already contained in the standard. To a certain extent, the catalogue of observation so treated represents systematically the ex- cellence and weight of all the observations concerned in the construction of the standard. To what extent this will actually be the case will depend chiefly upon two conditions: first, upon whether the standard catalogue has been made to represent, as consistently as possible, the sum total of observations having funda- mental value; secondly, upon whether the relation of the individual catalogue to this standard can be ascertained with the required accuracy. The latter condition is one whose importance is more liable to be overlooked. If the weight of determi- nation for the individual catalogue to be compared is feeble, or the number of pos- sible comparisons with the standard too few, then, no matter what the precision of the standard may be, the resultant effects of casual error in the individual catalogue may be so mixed up with the true systematic error as to vitiate the result. One of the distinctive features of the present work is that it aims to minimize this difficulty by furnishing a standard catalogue containing a very unusually large number of stars to represent it. The best determined standards alone are suitable for ascer- taining the systematic corrections of the catalogues of superior weight say those whose computed probable errors of position in either coordinate is not more than o"io or o'.'i2 at the epoch of comparison; while quite one-half of the stars in this General Catalogue are standards suitable for ascertaining the systematic errors of the general run of the larger catalogues of observation. It seems scarcely neces- sary to remark that there is no well-defined line of distinction between standard stars and others. What may be considered a suitable and sufficient standard for one purpose may not do at all for another. For instance, as standards in differential observations with meridian instruments at the present time one might safely decide that where the probable error for position in 1910 is given as "08, or less, the star-place is sufficiently accurate for the most refined use. Such stars might be termed primary standards. But for the less exacting class of zone-observations, or for miscellaneous observations, it may be considered that a probable error of the standard for 1910 of "12, or even "15, could be tolerated; since it is rarely the case that the probable error of a single observation would not be at least twice that amount. XII PRELIMINARY GENERAL CATALOGUE OF STARS FOR 1900 An account of the methods by which this standard catalogue was constructed, in reasonable conformity with the foregoing requirements, is contained in a series of papers published in Vol. XXIII of the Astronomical Journal. (Subsequently collected and reprinted under the title: Catalogue 0/627 Principal Standard Stars.) The successive approximations required in extending the number of stars contained in the Standard Catalogue, the estimate of value of each catalogue of observation as an original, or independent, source of determination, and the devices employed in the treatment of individual catalogues and in the combination of one with another, are there set forth, probably in sufficient detail to permit the formation of an inde- pendent judgment as to the character of the result. In much the same way the arrangement in chronological order of the systematic corrections of Appendix III (this volume) zone by zone will afford a rough means of estimating whether the system of the standard sufficiently well represents at various epochs the catalogues having value as independent sources of knowledge as to star positions. In this connection, however, it should be noted that this method will not give reliable information as to an effect upon the stars of an incorrectly assumed motion of the equinox. This requires a special investigation. In the present work the equinox determined in 1872 by Professor Newcomb has been adopted. (See : On the Right- Ascensions of the Equatorial Fundamental Stars, by Simon Newcomb, Washington Observations, 1870.) This probably requires material revision; but any such revision would affect all the proper-motions in right-ascension by a constant quantity. Furthermore, it should also be noted, as to the declinations, that pairs of con- temporaneous catalogues, one emanating from an observatory in the Northern and the other from an observatory in the Southern hemisphere, have been treated together in the present investigation for mutual correction of their results, previously to their introduction into the formation of the Standard Catalogue. Such pairs were formed, for example, from Camb 30 and Cape 33, Grw 60 and Cape 60, Grw 64 and Melb 70, and from many others suitable to the purpose. The comparison of the members of these pairs gave rise to equations for the determination of correc- tions to the refractions adopted in the reduction of the respective catalogues. It may well be urged that no series of determinations of star-declinations can be criti- cally regarded as sufficiently independent that rests upon a system of refraction- corrections determined at another observatory, for another horizon and for another exposure of the thermometer. But in spite of certain technical objections, it can scarcely be contended that the combination of contemporaneous results from north- ern and southern observatories in pairs (Ast. Jour., 540; also Declination 0/500 Stars, Boss) in the manner and for the purpose herein indicated, results otherwise than in a very decided increase in the value of each of the catalogues as sources of absolute determination of star-declinations. The preparation of the Catalogue 0/627 Principal Standard Stars was only the foundation structure in a process that has since been continued and elaborated. It may be well to remark here, that the utmost circumspection was required during these successive enlargements of the Standard Catalogue that, in the positions of the stars successively added to it as secondary standards, the original system should be INTRODUCTION XIII preserved. In other words, the systematic correction of a catalogue of observation compared with the corrected catalogue of 627 standard stars should result the same as it does from comparison with the additional standard stars, within admissible limits of casual error. / MAGNITUDE-EQUATION. Another special point in relation to this standard catalogue, as well as to the catalogue in general, may appropriately be mentioned here, since it constitutes a departure from the practice that has heretofore prevailed. An attempt has been made to produce published right-ascensions that shall be free from the effect of magnitude-equation. The magnitude-equation is a well-established effect in conse- quence of which the observer at the telescope ordinarily registers the transit of a faint star later than he would that of a brighter star actually in the same place. The equations of the different observers are by no means the same, and there appear to be a very few whose magnitude-equations are very near zero. The general aver- age of all equations appears to be not far from ^007 per magnitude on the historic scale (log. light ratio .36), or ?oo8 on the Pogson scale (log. ratio, .4). Furthermore it appears that the equation for observations by chronographic registry is not very different from that for observations by eye-and-ear. (Ast. Jour., 536.) From this it would appear that determinations of proper-motion in right-ascension would not be very sensibly affected by the neglect of correction for this equation in the past and present ; but that the right-ascensions of the fainter stars would generally come out too large relatively to those of the brighter stars, and in a different degree for different observers. For the purposes of a standard catalogue this is a matter of some importance, since stars of different magnitudes, in the case of many observers having equations different from the average, would give systematically different clock corrections. Since the published discussion of this effect (A. J., 536) the investigation of the magnitude-equations and the corresponding corrections required to eliminate this effect from the individual catalogues of observation has been continued here more critically and upon an enlarged scale. The essential outcome has been substantial confirmation of the earlier results, as will be seen by consulting the tables of Aa y in Appendix III. The magnitude-equation of the Catalogue 0/627 Principal Standard Stars was found to be ?oo77^Mf 3.5), where M represents the magnitude of a given star on the Pogson scale (A. /., 536). This is equivalent to ?oo6g (M 3.5) on the mag- nitude-scale of this Preliminary General Catalogue, the magnitudes for which, when brighter than 6"6, are taken from a manuscript catalogue of normal magnitudes prepared by Dr. S. C. Chandler, based upon a combination of substantially all useful material contained in the various uranometries and photometric determinations, adjusted to the historic scale. Accordingly the right-ascensions of the Catalogue 0/627 Principal Standard Stars, in addition to other revisions for many of the stars, were corrected by ?oo69 (M 3.5) (where M was adopted from the present work) and were then transferred to this Catalogue. For all stars not included in that XIV PRELIMINARY GENERAL CATALOGUE OF STARS FOR 1 900 list, the corrections Aa a for magnitude-equation were applied to the individual catalogues of observations and treated like any other form of systematic correction. The resulting right-ascensions as printed in the Catalogue are supposed to be free from this effect. The magnitude, 3^5, was chosen as the zero of reference, so that the mean equinox of the right-ascensions would not be sensibly disturbed. Since the basis of these determinations was laid (A.J., 536), it has been possible to apply several further independent tests of considerable value in estimating the freedom of this catalogue from errors dependent on magnitude of the star. Tucker's determination of his magnitude-equation for the right-ascensions of the Piazzi- stars affords one such test; OertePs determination of right-ascensions with the Repsold micrometer at Munich (Miin oo) presents another; and Ktistner's right- ascensions at Bonn (Bonn oo in Manuscript) offer still another. Arranging the comparisons in the order of magnitude there was obtained for the respective cata- logues, in the sense P.G.C.- Miin oo, etc. : MUNICH 1900. LICK 1900. BONN 1000. M No. of Stars. Obsd.

More testimony of the same kind has been derived from the recent right- ascensions of Albany and the Cape, where the respective observers applied their respective magnitude-equations in the reductions. Several courses are open to observers who may wish to use this standard cata- logue in observation of right-ascension, (i) Observers can use a self-registering micrometer. (2) They can determine their own magnitude-equations during the progress of their observations and free their transits from the effect of the equation. (3) They can assume their equations to be ?oo69 (M 3.5), the mean of all observ- ers. In these cases the right-ascensions of the present Catalogue are ready for use as standards. If no attention is given to the magnitude-equation, instead of correcting the transits for mean equation, we can evidently correct the present Catalogue by + ?oo69 (1^ 3.5) in order to make it systematically conform, in an approximate way, with standard catalogues heretofore in use that are uncorrected for magnitude-equation. SELECTION AND IMPROVEMENT OF STANDARDS. The Catalogue gives for each star, both in right-ascension and declination, the weighted mean epoch of observation from combinations of all catalogues ; the prob- able error of the coordinate at this mean epoch ; the probable error of the centennial motion; and, finally, as a matter of convenience and check, the probable error of INTRODUCTION XV the coordinate when reduced to 1910. From inspection of this information one may determine what stars are best suited for use as standard stars, when both elements of qualification for standard stars are considered. The precision of the position at a given epoch is compounded of the precision at the principal, or mean, epoch with that of the proper-motion. If we construct a standard catalogue that is designed to remain in efficient use until 1920 (say), then its predicted probable errors during its period of use up to 1920 are of even greater interest at the later than for the earlier dates. The data given in the present Catalogue provide for the computation of a predicted probable error of position for any required epoch ; and whenever the resulting probable error is not much over o'.'3, this prediction as to precision should be relatively a fair approximation to the truth. This information, however, may frequently be required in relation to stars which would not now be regarded as well enough determined to be employed as standard stars in zone or regional observations at fixed observatories, but which might be made into useful secondary standards through special differential observations based upon the principal standards, and contemporaneously with the zone-observa- tions themselves. This method has been advantageously employed at the Dudley Observatory (1896-1901, A. /., 499). The data of the present Catalogue would facilitate the selection of such standards in such a manner that the new secondaries might be chosen in view of their future as well as present usefulness. Not only is the selection of such stars herein facilitated, but the preparation of accurately pre- dicted positions for them is made comparatively easy. The results contained in the present Catalogue are supposed to be exhaustive of existing determinations to the extent indicated in the foregoing list of catalogues employed. Additional weight of observations, not contained in that list, can easily be incorporated with the catalogue- data in such a manner (as will be explained hereafter) that the final results will virtually represent a complete solution of all the observational equations that were formed in the present work, together with those from the additional material. Thus the work here done, if considered satisfactory, need not be duplicated except in special cases. As another illustration of the value which an approximate knowledge of the degree of precision reached may have, take the selection of stars for determination of latitude. In the Catalogue the probable errors in declination are given for 1910; and they can easily be computed for other dates. This is of very great advantage in facilitating choice of the best determined stars. Furthermore, considering the great precision of instrumental results in latitude-observation, the precision of the final result of a series of latitude-observations may depend more upon the precision of the star-places than upon that of the instrument. The present Cata- logue furnishes fairly reliable estimates of probable error for each declination, enabling this element to be taken into account in latitude-reductions in order to reach the most probable result. At the same time the results of later observations of such latitude-stars can be easily and accurately incorporated in a revision of the determinations recorded in the present work, as will be shown later on. It should be specially noted that for stars of the class represented by the weaker one-third of the present Catalogue, the probable error of the predicted position increases much XVI PRELIMINARY GENERAL CATALOGUE OF STARS FOR IQOO more rapidly with the time than for the standard stars. For instance, there is a large number of stars whose right ascensions or declinations have the greatest weight somewhere between 1880 and 1890, or later, with probable error of cen- tennial motion, o"6, or more. The manner in which the probable error increases for this class of stars can best be illustrated by an example. For this purpose take No. 26 of the Catalogue, for which the probable error at the epoch 1888.3 i s '^S and of the centennial proper-motion is i"o6. The following table gives computed probable-errors and weights (unit of weight corresponds to p.e., "3) for the respective epochs. STAR No. 26 IN DECLINATION. Year. p.e. Weight. 1888.3 '.'13 5-3 1900 .18 2.8 1910 . 26 1-3 IP'S -31 0.9 1920 .36 0.7 Thus a weight of determination that was 5.3 in 1888 has fallen to one-fourth of this amount in 1910. That is below the weight of the mean of two observations in the more precise of modern catalogues of observation. This rapid diminution of weight seems worthy of mention here, because its existence often appears not to be specifically and properly appreciated even in works aiming at precision. RECAPITULATION. Before entering into detail in reference to the proper understanding and use of the present Catalogue we may venture to recapitulate the statement of its principal characteristics as follows: 1. The primary object of the Catalogue is to give the proper-motions of the stars as they result from a precise discussion of all readily available observations in each case. 2. It aims, also, to furnish a Standard Catalogue that shall be practically exhaustive of the material of observation both in extent and in thoroughness of discussion, and which shall include all stars likely to be needed at present for standards in zone- observations and the like. 3. It gives the right-ascensions of the stars substantially free from the error arising from magnitude-equation. 4. It furnishes with each star the means for a complete estimate of the probable accuracy attained in respect to the catalogue position and motion of that star. 5. As has been intimated, and as will later be shown more specifically, the catalogue-data offer convenient means for incorporating with due weight, for purposes of revision, observations additional to those on which the catalogue results are based. INTRODUCTION XVH THE COLUMNS OF THE CATALOGUE. In order to facilitate a proper and intelligent use of the Catalogue let it now be considered systematically in detail. The first column on each page gives the current number for reference. There are 6188 numbers in all. ADOPTED NAMES. The second column on the left-hand pages contains the adopted names or desig- nations of the respective stars. This Catalogue makes no claim to erudition, or authority, in this respect. At the outset it was decided that the time and labor required for a critical and consistent treatment of the constellations could not be afforded. Except for a few of the brighter stars, there appears to be no single authority or rule of procedure in this respect that is so generally accepted as prac- tically to require obedience. The practice of meridian -observers, and of others who have occasion to make use of star-names, seems to make this clear. Therefore, in devising nomenclature for the stars of this Catalogue the author has felt himself absolved from any attempt to found a system capable of defense on historic grounds ; but he has felt free to adopt that which seemed to him most convenient, fitting, and simple for his purpose. Yet certain quasi-general principles were kept in mind by the author in selecting precise designations for the individual stars. It was decided, very naturally, where a star is brighter than 6"o and has a virtually undisputed claim to a Greek letter, unmodified by accent or subscript, that this should be adopted. In case of some stars where this qualification could not be asserted the Greek letter has still been retained. Of faint stars, the names X Ursae Minoris and o Octantis are retained, since many meridian-observers must have become well accustomed to the designations. On the other hand, neither the name, "y Antliae," sometimes employed for No. 2764 of this Catalogue, that is of 7^3 only, nor the name " Piscis Australis" for No. 5802, a star of 6^8, seems to serve any useful purpose. If the adoption of a Greek letter is to be regarded as a distinguishing mark of brightness, such designations of Greek letters for faint stars tend to mislead and confuse, since the great majority of stars fainter than 5^0 and even such stars as L 3910, 2^8, and Br 3062, $8, are not designated by Greek letters. The practice of assigning the same Greek letter to several stars of a constellation, relying on added accents or subscripts to distinguish the separate stars, does not seem very convenient and has been carried rather far in some instances. Thus the Greek letter T is attached to nine bright stars in Eridanus, the letter ^ ten times in Auriga ; and there are many instances where the same letter is employed more than twice to designate stars in a given constellation. There already exists a tendency in such instances to discard the subscripts or accents and to reserve the use of the letter to the brighter star, especially if this is decidedly above the sixth magnitude. This tendency has been obeyed in the present work, where precedents XVTII PRELIMINARY GENERAL CATALOGUE OF STARS FOR IQOO exist, and several changes have been here independently made. Thus we have ' and f 2 Ceti ; in the present work ' has been discarded and the exponent taken from 2 , even though the difference of magnitude is small. There are several other instances of the same kind. These subscripts or exponents have sometimes been retained in the cases where the two stars may be regarded as constituting a close naked-eye double, as Nos. 1045-1046, l and 2 Tauri (dist. 6'). As a rule the practice of employing the numbers of Flamsteed, Hevelius, Bode, or Gould with the name of the constellation as a designation has not been followed in working up the second column of the Catalogue. There are numerous cases where the Flamsteed numbers have been misapplied ; there is no uniformity in assigning the exact boundaries of the constellations; and in the use of the letters B, H, and F we have a fruitful source of inconsistencies and errors, especially in view of the nearly universal practice of omitting the letter " F " to indicate that the number is Flamsteed's. The letters "B" for Bode and "H" for Hevelius have often been dropped. It was decided to get rid of the critical labor involved in unprofitable research upon these names by discarding them altogether. Yet, in a few instances, such familiar designations as 70 Ophiuchi, 61 Cygni, and 51 H Cephei, have been retained ; and in the column of remarks the Flamsteed and Gould numbers with constellation names (mainly quoted from the catalogue of the British Association) are given as convenient synonyms. The use of the Roman alphabet with constel- lation names, except for naming variable stars, seems to be open to very serious objections. Such letters are sometimes given in the column of remarks, but are excluded from the second column. The similarity of such letters as a and a, i and i, K and x, o and 0, v and v, CD and w, either in manuscript or print, has been the source of much confusion and of what should have been unnecessary labor. Whatever have been the faults of naming the northern stars, the case is far worse for the southern sky. Here it has been decided to cut loose from all traditions and to follow the constellations and Greek letters as they were given by Gould in the Uranometria Argentina, with modifications as to the employment of letters with exponents similar to those adopted for northern stars. Roughly, this practice takes effect at about 23 of declination, and near that parallel inconsistencies are neces- sarily introduced that are not, however, regarded as of any particular moment. In the column of remarks the Gould numbers and constellations have usually been given for the far southern stars. The simplest mode of designation (and in many respects the most natural for a catalogue like this) is to give, in abbreviated form, the name of and number in some well-known star-catalogue in which the earliest observations of precision upon that star are found. Thus, "Br 3208" (Bradley), given as a designation for the first star in this Catalogue, is specific and probably more convenient as a means of identification than would be "33 Piscium," by which this star is often designated. Lacaille's zone-observations at the Cape of Good Hope constitute a nearly complete survey of the brighter stars of the southern sky. Comparatively few stars brighter than 7*0 have been omitted. These numbers have been very extensively quoted in star-catalogues. Therefore, although the catalogue of Lacaille's observations is INTRODUCTION XIX very far from being a catalogue of precision, it does offer a convenient means for applying a designation for the great majority of southern stars. Piazzi and Groom- bridge with numbers are also convenient designations. Failing all these which have been enumerated in the foregoing, the practice has been to employ the number in an early catalogue, avoiding those in which there are few stars. If the star occurs in no catalogue of precision earlier than about 1875, the number in Lalande's or Bessel's zones, and occasionally from other sources, has been employed. When, as in the case of Piazzi and Lacaille, both numbers exist for the same star, the Piazzi number is preferred for stars north of 30 and the Lacaille number for those south of that parallel. It would be tedious, however, to enumerate all the details that have governed in the choice of names for stars not frequently observed. To the name in the second column is sometimes appended a letter. When m is thus appended, it usually means a double star observed in the mass ; but where the star is wide and the components distinct, or where the components are of nearly equal brightness, m more commonly indicates the mean. Usually, the notes give an indication as to what is probably meant. For a great proportion of close double stars, for which the difference of magnitude between the two components is less than 3" (say), it is rather difficult to determine to what point the observation refers. For several binaries an attempt has been made to determine the relative masses of the components. In such cases the letters c. g. (center of gravity) are appended to the name in the second column ; the catalogue-position is intended to be that of the center of gravity. Particulars relative to such stars are to be found in special notes contained in Appendix II. MAGNITUDE OF THE STARS. The third column on each left-hand page contains the estimated magnitude of the star. For all stars indicated as of 6"5 or brighter (with trifling exceptions), the magnitudes are taken from a manuscript catalogue furnished by Dr. S. C. Chandler. When approached for advice in the matter of star-magnitudes, Dr. Chandler very generously offered to place at the disposition of the author the results derivable from his extensive manuscripts relating to the magnitudes of the brighter stars. This was followed with catalogues containing magnitudes of all stars in either hemisphere deemed by Dr. Chandler to be 6^5, or brighter. These were based upon the collation of the results from all the principal uranometries and photometric results. Furthermore, the "historic" or "natural" scale (approximately that of the Uranometria Nova of Argelander) had been adopted for the normal; and the systematic corrections necessary to reduce the Uranometria Argentina and various photometries to a normal had also been ascertained. Through the photometric observations the normal scale had been fixed at the light ratio whose logarithm is OT^6. One of the essential features of the historic scale is the magnitude 6^0, which in the course of generations, and through the data collected in successive uranome- tries, had come to be quite a definite thing. In establishing the gradation above and below this datum (near Potsdam 6"o) Dr. Chandler appears to have aimed to keep XX PRELIMINARY GENERAL CATALOGUE OF STARS FOR IQOO in touch with the scale of the Uranometria Nova and Banner Durchmusterung with some reference to the historic glfo, which through the estimates of Bessel, Argelander, and others had also come to have a fairly definite (though not absolutely rigorous) meaning to the great body of astronomers. It is to be hoped that Dr. Chandler, at some future time, will give an exposition of the methods by which he has reached results of such great importance and value. Meanwhile, in view of the most liberal and generous authorization of Dr. Chandler, his normal system may best be defined here through some of his tables of systematic corrections. The logarithm of the ratio of brightness for one magnitude in Chan- dler's Normal Uranometry is stated by him to be .36, differing from Pogson's scale (log. ratio = .4) now in extensive use. As will appear, Chandler's system is nearly equivalent to the Potsdam system for "GW" (yellowish white) stars plus .08 (M 6lfo), where M indicates the normal magnitude of a given star. It will be noted that Dr. Chandler deduces decided systematic corrections on account of color. ADOPTED CORRECTIONS TO POTSDAM PHOTOMETRY. ADOPTED CORRECTIONS TO HARVARD PHOTOMETRY.

For the fainter stars as many as possible were computed at the Dudley Observatory with the aid of the foregoing tables of systematic correction. During this process the generally excellent agreement of the Harvard and Potsdam corrected results attracted marked attention. Down to the limit of the tables, 7^0, the systematic corrections appear to produce very satisfactory agreement between the Harvard and Potsdam results. Below this limit the corrections were roughly extrapolated for Potsdam and were assumed to remain unchanged from 7*0 for Harvard. For a large part of the stars in this Catalogue noted as fainter than 7 "o, the magnitudes depend upon rather uncertain eye-estimates, such as those con- tained in the Durchmusterungs and in certain catalogues of meridian-observation for which estimates of magnitude are made with some care. These magnitudes are of course subject to errors very much exceeding those attributable to the magnitudes based upon Harvard and Potsdam photometries. In the case of double stars the differences of magnitudes of the components were mostly adopted from the Mensura Micrometrica of Struve or from the photometric measures of the Harvard Observatory (H.C.O. Annals, Vol. XI). However, this part of the work can lay no claim to critical exactness. It may not be superfluous to note again that a magnitude-equation determined in strict conformity with the Pogson scale (log. light ratio, .4) should be multiplied by 0.9 in order to reduce it to the scale of this Catalogue. The authority for noting variable stars has been Chandler's Third Catalogue, and usually the limits of variation have been adopted from that authority. XXH PRELIMINARY GENERAL CATALOGUE OF STARS FOR IQOO RIGHT-ASCENSIONS AND DECLINATIONS. The fourth column on the left-hand page contains the right-ascension for 1900 (reduced to that epoch with proper-motion, so that both equinox and epoch are 1 900) ; and the second column on the right-hand page contains the corresponding declination. The most important general points relating to the computation of these quantities have been set forth in preceding paragraphs of this Introduction. The list of star-catalogues employed has been given, as well as a sketch of the means employed to secure the greatest possible immunity from the effects of sys- tematic error. (See also Ast. Jour., Vol. XXIII; also Catalogue 0/627 Principal Standard Stars.} A few words about the methods employed in the computation of the individual positions and motions may be useful. For each star, from a prelimi- nary estimate of position and annual variation for 1875, an ephemeris covering the required dates of observation for that star from 1755 down to the present was formed and carefully checked. In expanding these ephemerides the third term of precession was taken into account. For stars of greater declination than 82, standard dates, at suitable intervals, were derived through use of the trigonometrical formulas, as given by Newcomb; and other intermediate dates were interpolated from these. Then conditional equations were formed by means of the corrections to the ephemeris given by each star-catalogue containing a position of that star. These conditional equations involved unknowns for correction of the before-mentioned assumed positions and annual variations for 1875. The unit of the coefficient of proper-motion was taken as twenty-five years, in order to render the coefficients of the normal equations fairly homogeneous. In forming the absolute terms of the conditional equations, systematic corrections of the catalogues of observation were employed. In the early stages of the work these corrections sometimes differed slightly from those given in Appendix III, but the residual effect upon the posi- tions and motions is negligible. The conditional equations were also carefully weighted in conformity with the tables of weights contained in Appendix III. The normal equations were solved in the usual manner, and the resulting corrections were applied to the quantities assumed as the basis for correction. All the operations were duplicated, or adequately checked. The catalogue positions in right-ascension for 1900 are supposed to be cleared from the effect of magnitude-equation, as already stated in this Introduction. For several binary stars, where orbits of a fair degree of accuracy have been computed, and where meridian-observations exist in sufficient weight to make the attempt worth while, computations have been made to obtain an approximation to the relative masses of the two components. The respective radii of the two com- ponents in their orbits around the center of gravity lie on diametrically opposite sides of that common center; and the ratio of these respective radii to each other and to their sum remains constant in all parts of the orbit. Therefore, to obtain this ratio it is simply necessary to take advantage of the fact that the form of the orbit of the principal star around the center of gravity is the same as that of the INTRODUCTION XXIII relative orbit. If the ratio of the major axis of the actual orbit of the principal star around the center of gravity to the major axis of the relative, or ordinary double- star, orbit be denoted by r, and if A a and A 8 be the coordinates in right-ascension and declination respectively of the orbital motion of the fainter around the brighter component, then the coordinates of the motion of the principal star around the center of gravity will be rA a and rA 8 respectively. Introducing these quantities also into the ordinary equations for determining the position and motion of the star, A a and A 8 will be known coefficients to be computed from the adopted orbit of the binary, and r will be an unknown, to be determined from the equations of condition, along with the corrections to assumed position and motion of the center of gravity. If we take for the unit of mass that of the brighter star, then the mass of the fainter star will be i r Knowing r, it now becomes possible to reduce the observations of each compo- nent to the center of gravity ; and it is the position and motion of this e.g. that is given in the Catalogue. In Appendix II there are given for each of these stars the quantities necessary to be added to this position of the center of gravity for a given date in order to have the corresponding position of either of the components for that date. Following is a list of the binary systems thus treated. The ratio of masses is given in terms of the mass of the brighter star as the unit. TABLE OF BINARY STARS WITH ADOPTED RATIO OF MASSES.

Those for 1732, 2008, and 3735 are quite precise, and those for Nos. 2984, 3307, 4246, and 4571 may be regarded as fairly satisfactory. There appears to be no case in which the fainter companion can be asserted with high probability to have a larger mass than that of the brighter component. In the case of No. 6172 the computation is scarcely warranted by weight of meridian- observations; and the result is very likely to have been seriously influenced by fortuitous grouping of errors. Notwithstanding the care exercised in the computations for binary stars, the uncertainty of the result for predicted, or extrapolated, position and motion of each XXIV PRELIMINARY GENERAL CATALOGUE OF STARS FOR 1900 of the individual components is materially greater than for single stars of the same class. Undoubtedly this is largely owing to the inevitable uncertainty of the orbital elements adopted in these computations (especially when micrometric observations have been extended over a part only of the orbital period) ; but in an important degree, also, uncertainty arises from decidedly individual systematic errors in meridian-observations of one component when the other component is distinctly visible. Accordingly, the particulars regarding probable error are omitted for these stars. At the same time it may be stated that the larger part of these stars, but for periodic variability of motion, would have belonged to the higher classes of standards. Special computations were made for Groomb 1830 and 61 Cygni for the purpose of detecting a foreshortening or perspective effect in the annual motions of these stars. In both of these instances the computations seem to have been measurably successful in exhibiting such an effect, as will be seen from the detailed notes con- cerning these stars in Appendix II. In the case of the two components of 61 Cygni, the estimated effect of mutual curvature of the components is also included in the computation. These effects tend to modify the centennial variations of the proper- motions and annual variations ; and these centennial variations thus modified are adopted in the catalogue-data for these stars. As already explained under "Adopted Names," whenever the letter m is ap- pended to the name in the second column, it means that the pointing of the observers has probably been made either upon the mass of light, or upon the mean when the components are either wide or of nearly equal magnitudes. Notes are given in some cases ; in others there must exist more or less doubt. Usually, however, the uncertainty is not very serious, especially where the difference of magnitude is very large. As a consequence of the discussion that relates to probable corrections required for the motion of the equinox and precession adopted in this Catalogue, described later under "Proper-motions," the right-ascensions require a correction of +''0079 (71850), in consequence of the deduced correction of + "79 to the centennial motion of Newcomb's equinox, N 1; to which the right-ascensions of this Catalogue correspond. This correction becomes +f 026 for 1900; and this is the common correction of all the right-ascensions of this Catalogue, if it is desired to make them correspond to the motion of the equinox so corrected. This probable correction receives some support from Newcomb's discussion of the correction required for N!, so far as it is indicated by the Washington and Greenwich observations for several years around 1897. (Ast. Jour., No. 498, Vol. XXI, p. 141.) The following cor- rections of the equinox, N u from observations of the sun are there derived : From Washington + ?0 53 From Greenwich +^005 1896 The mean of these, + ?029, is very near that otherwise found in the foregoing. Finally, as will be seen later, it is of the utmost importance that the very great differences of accuracy in the catalogue-positions and motions of different stars be not overlooked; and especially that due attention be given to the relative degree of reliability with which desired predictions for individual stars can be effected. INTRODUCTION XXV MEAN EPOCHS. The fifth column on the left-hand pages and the third on the right-hand pages of the Catalogue contain respectively the mean epochs in right-ascension and declina- tion. These are the means by weight (App. Ill) of the epochs of observation con- tained in the individual catalogues of observation relating to the star in question. The mean epoch has this useful property that, if we reduce the separately observed right-ascensions and declinations from their respective mean epochs to that given in this Catalogue, and combine the resulting positions by weights identical with those employed in forming the mean epoch in this Catalogue, the resulting coordinates will be independent of the proper-motion employed. For any date before or after this, the probable error of the computed position (employing the elements of this Catalogue) will be compounded of the probable error at the mean epoch and the probable error of the motion during the time elapsed. The statement of the mean epoch also serves to indicate, in connection with the probable errors, the general distribution of the observation available in the case of each star. Thus, if the prob- able error of the proper-motion is relatively large in comparison with the p.e. at epoch, then a very early mean epoch would indicate that the star has been neglected in recent times ; and under the like conditions, if the mean epoch is relatively late, that the star was neglected in earlier times. If the mean epoch is so early as 1860, for instance, we have already in 1910, as a component of the probable error of position for that date, one-half of the probable error of centennial variation. For illustration, take No. 44 in declination. The mean epoch is 1860.0; the probable error of declination at mean epoch is "19 ; the probable error of centennial proper- motion (100 /*/) is ''64; therefore that part of the probable error of declination for 1910, due to probable error of centennial proper-motion, is 0.5 x'.'64= "32. And this is very much more important than the probable error of declination, .19, that attaches to the position at mean epoch 1860. The probable error of the declination for 1910 is evidently: ^(.i9) 2 +(-32) 2 = "37; so tnat the weight for the catalogue-declination reduced to 1910 is only about equal to that of a single good meridian-observation. ANNUAL AND SECULAR VARIATION AND THIRD TERM OF PRECESSION. The sixth, seventh, and eighth columns on the left-hand page and the fourth, fifth, and sixth columns on the right-hand page contain the elements necessary for reducing the catalogue-positions from 1900 to any required epoch. Under '^d t." (third term) the element of geometrical precession that depends on the third power , , itPa id?8 of the time is given. It is usually quite closely equal to - , or - . In a few cases the proper-motion has been taken into account in computing this term. If we denote the fraction of a century from 1900 by T (minus, reckoning back), then the effect of the third term upon the deduced position is: r 3 x (3d t.). In the sixth column is given the annual variation in right-ascension, and in the fourth, on the right-hand page, the annual variation in declination. Respectively XXVI PRELIMINARY GENERAL CATALOGUE OF STARS FOR IQOO in the columns following these, and not separated by a rule, are found the secular variations of the annual variations. These are different from the geometrical secular variations of the precession, and again different from the variation of the precession as affected by proper-motion. For the sake of clearness, let us begin with the secular variation of the proper-motion, A/n (tenth column, left-hand page) and A/t' (eighth column, right-hand page). We have: A/i = [7.98762] p cos a tg 8 + [6.81 1 53] // sin a sec 2 8 + [6.9866] /*/*' tg 81 , . > A/i' = [9.16371 n] p, sin a -I- [8.7367 n] /x 2 sirJS j The numbers in brackets are logarithms, computed after Newcomb's constants of precession. To denote equations (A) when terms in (/i/x') and p. 2 are omitted, put A'/i and A'/x' respectively. Let p and />' denote the precessions. Then we shall have: Geometrical sec. var. = * A/ True sec. var. of precession = -* + A'/i. Sec. var. of annual variation = * + A'/A + A/*. A/ (B) Accenting p and p., we have the equations for declination. Usually we shall have with sufficient accuracy for the secular variation of the annual variation 77 + 2 A'/u,, Of since the omitted terms in A'/x. and A'/x' are usually insensible. In the computa- tions of annual variations for the Catalogue no assumption was made as to the precession; but in computing the secular variation such an assumption becomes necessary. Therefore Newcomb's constants were adopted and formulas (A) and (B) were employed. In the practical computation of ^ and -%- manuscript -j' l\t tables were formed for declinations less than 60, and the terms of (A) were con- veniently tabulated in part. For stars of numerically greater declination than 82 or 83, use of the trigono- metrical formulas was made to form standard epochs either twenty-five years or five years apart, according to need. From these dates interpolation was effected by means of the computed annual and secular variations, with third terms roughly derived from differencing the latter. For these stars in the Catalogue the third term is not given, and one decimal place is dropped in printing the annual and secular variations. At the same time, as a matter of convenience for those wishing to compare results of observation with this Catalogue, positions, motions, and secu- lar variations have been computed for certain standard dates up to 1925, as given in Appendix I. For the purposes of interpolation, sufficiently accurate values of the third term can be derived from the differences of successive secular variations. The trigonometrical formulas and constants of Newcomb were employed. (See The Precessional Constant, pp. 73 to 76.) INTRODUCTION XXVII For the convenience of the reader a table of constants is here given adapted for reducing a star-place given for 1900 to other dates preceding and following.

The ninth and tenth columns on the left-hand pages give the proper-motion, fi, in right-ascension, and its centennial, or secular, variation, 100 A/x,, in units of the fourth decimal ; correspondingly, the seventh and eighth columns on the right-hand page give the proper-motion, /u/, in declination, and its secular variation, iooA//, in units of the third decimal place. The proper-motions are derived by subtracting from the annual variations the precessions computed from Newcomb's constants for 1900. They are: Precession in R.A. = p = + 3507234 + i!33646 sin a tan 8 Precession in decl. p'=+ 2o'.'o468 cos a In the practical computation, Becker's tables (Vol. II, Strassburg Observations') or Downing's tables for 1910 were employed. It did not seem necessary to print the computed precessions ; they can readily be recovered for any star by subtracting the proper-motion from the annual variation. 100 A/i and 100 A/n,' were computed by means of formulas (A) under "Annual and Secular Variation, etc." in the fore- going. As already stated in the earlier part of this introduction, the ascertainment of proper-motions of the stars constituted the chief motive for the labors that led to the production of this Catalogue. In pursuance of this object, the next step would naturally be to find out what corrections of the adopted precession and of the adopted motion of the equinox are most consistent with the results for annual varia- tions in this Catalogue. A tentative investigation indicates that the proper-motions in right-ascension and declination as printed in this Catalogue require corrections of +?ooo2i ?oooi5 sin a tan 8 for p, and "0023 cos a for pf This implies a correction of Newcomb's luni-solar precession for 1875 of +'.'0058 (annual) ; of his planetary precession (annual) at the same epoch, of +"0006; and a further correction to the right-ascensions of Newcomb's system, NI, which is the basis of this Catalogue, of +''0079 (T 1850), T being expressed in years. The deduced correction for Newcomb's m is : + '^0058 cos at "0006 = + "0047 ; and of Newcomb's n is : + '.'0058 sin = + "0023, in which IOO ; then if e be the probable error of the right-ascension at the mean epoch and e M the probable error of centennial /t, while e r represents the probable error for the required date, we shall have: In the case of Br 3208, this becomes: r 94 = e r = VC + ('.'296 x .27)' If we choose '.'30 as the p.e. of the unit of weight, as has been the case with all the computations for this Catalogue, we shall have as the weights of catalogue-right- ascension at the respective epochs: r WEIGHT. 1870.4 1900 1910 36.0 IO. I 6.2 Thus it is seen that the weight of the predicted right-ascension is rapidly falling, until in 1910 it has only one-sixth the value it had in 1870. By 1920 this weight will have fallen still farther to 4.4. Thus we are able to obtain a very precise idea of the manner in which the precision of the determination for a given star is varying information that is specially important in the case of a star used as standard in meridian-observations, or for any other purpose requiring high precision. The applicability of these probable errors has been repeatedly tested in the course of computations for this Catalogue, and they are believed to be relatively accurate, and quite certainly not too small in the mean. In order to secure the general reliability of these probable errors in the case of each individual star, they are not XXXII PRELIMINARY GENERAL CATALOGUE OF STARS FOR IQOO derived from the residuals for that star alone, but are computed from the weights resulting from the least-square solution, the probable error of the unit of weight having been verified from the residuals in the solutions of hundreds of stars. As with probable error in general, it may happen that abnormal residuals, or a favor- able "run of luck, " may cause the probable error computed from the residuals for a given star to be greater or less than the mean probable errors printed in this Cata- logue ; but it is believed that, in the long run, the latter are more reliable. It should be borne in mind, however, that probable error is not probable uncertainty. This latter may be as much as, or more than, four times the probable error. Computa- tion shows that we ought to expect that 43 out of the 6188 stars of the Catalogue will ultimately prove to be affected by errors equal to four times the printed probable error of position, and similarly for the probable errors of motion. But these will be the extremely unlucky cases, and, after all, they will be only about one star in 140. Not quite one-fifth of all the stars should be found to have errors equal to twice their probable errors ; and about one in twenty-three stars should turn out to have a real error three or more times the probable error assigned to it in this Catalogue. Then there are the mistakes, as distinguished from mathematical probable error. These may be classified for convenience as follows: (1) Mistakes in the star-positions as printed in the original catalogues of observation. (2) Mistakes of computation in course of preparing the data for this General Catalogue. (3) Mistakes occurring in the combination of data from these computations in order to form this Catalogue as printed. Doubtless all the catalogues contain undetected errors that may be termed mistakes, some of which have been discovered in the course of this work. The presence of such errors, notably in catalogues like Pi 1020, Madr 35, Arm 40, Madr 75, and others, has been frequently indicated to us by abnormal residuals. When it appeared that these might be five times as large as the computed probable error of the catalogue-positions for the particular number of observations employed, the residuals were rejected; but, since satisfactory probability that a discordance was really to be attributed to a particular catalogue would often be wanting in the case of many of the weaker stars, it must have happened in numerous instances that the catalogue-places as actually employed in these computations are still injuriously affected by undetected, material errors of observing record or of com- putation. The effect of such undetected errors, and of other well-known practical considerations, must have been to make the probable errors assigned to the weaker stars relatively less accurate than for the stronger stars, from which abnormal errors are more completely, though not entirely, eliminated. In considering this first point, however, it should be noted that, in computing the weights of observed star-positions (App. Ill) some of the effect of mistakes in the individual cata- logues is naturally included. As to errors in the computation for this work, very great care has been exercised to reduce the number of these to the lowest possible limit. The greatest part of this work has been absolutely duplicated, and all of it has been carefully checked. INTRODUCTION XXX1U Probably the most fruitful source of mistakes will be found to have arisen in the process of assembling the data arising from the computations in order to form the Catalogue as printed. In preparation for the printer's copy of the Catalogue the needed material from various sets of computations had been assembled on cards arranged in the order of right-ascension. The solution of the normal equations for each star had given corrections applicable to the assumed positions and annual variations f or 1 8 7 5 . Another process gave those to be applied to the assumed position and annual variation for 1900. The corrected positions and annual variations for both dates were copied on the catalogue-cards, together with other data relating to precession, proper- motion, etc. Then the corrected position for 1900 was rigor- ously reduced to that of 1875, with the elements provided for that purpose in this Catalogue. This served for the detection of several small errors in the original ephemerides, or in forming the corrected places. This process not only resulted in a satisfactory verification of the relative positions for 1875 and 1900, but at the same time it afforded a good check on the annual variations and a check against gross errors in the secular variation ; but it was, of course, ineffective as to errors common to the data for both 1875 and 1900. Various tests and checks have been employed to guard against any very important error of this kind, like errors of i' or i s . METHOD OF CORRECTING THE CATALOGUE-POSITIONS AND MOTIONS BY MEANS OF ADDITIONAL OBSERVATIONS. The probable errors already described may be made to serve a useful function additional to that of affording a criterion of the precision attained. From these probable errors may be recovered normal equations which, though not the same, are sufficiently equivalent to those from which the catalogue-positions and motions resulted. As an example, take No. i, Br 3208, or 33 Piscium, in right-ascension. We have: = "05, the probable error of right-ascension at the mean epoch, 1870.4 ; = '.'27, the probable error of centennial fi. If now we put for the prob- able error of the unit of weight, "30, and if we make a quarter of a century the unit of time from the mean date, we shall have as normal equations for correction of the Catalogue for 1870.4: 30.0 Aa + .oA//, = !ooo o Aa + 19.8 A/i = .000 Acto is the required correction of the right-ascension for 1870.4, the catalogue mean epoch, and its coefficient is the weight corresponding to e . A/AO is the required correction of the catalogue-value of 25 /t, and its coefficient is the weight corre- sponding to ^- Now suppose that a determination of the right-ascension of this 4 star is to be made in 1909.9, and that the weight of that determination is to be 6.0. Suppose this determination corrects the catalogue right-ascension by + -030. Then we shall have as a conditional equation from this determination : -4 A +!030) or 2 5 XXXIV PRELIMINARY GENERAL CATALOGUE OF STARS FOR IQOO Proceeding in the usual manner, we shall have to add to the first of equations (D), 6.oAoo + 9.48 A/i = +?i8o and to the second of equations (D), 9.48 Aoo+ 14.98 A/i = + !284 The new normal equations become: 36.0 Aoo + 9.5 A/x = + fi8o 9.5 Aoo + 34.8 A/*= + ?284 The solution of these gives = + foo3 (for 1870.4) A/u, = + ? The new mean epoch is 1877.0. For 1900 we should then have Aa= + !oi2, and consequently : ("Right-ascension =o h o m 13^013 1900 I Annual variation = + 3*0712 [Proper-motion = !ooio The probable error at the epoch, 1877, ^ "5 (weight 36), and the probable error of centennial motion is "21 (weight *- = 2.02). The probable error for 1910 is now "085 instead of "12 given in the Catalogue; consequently the weight for that date is nearly doubled. Owing to the rounding of the probable errors on the second decimal place, the weights for position at mean epoch and for centennial proper-motion may differ somewhat from the actual results from the solution-normals from which the catalogue-results were derived. But this difference will be larger for the best- determined stars, and there it will be of no material consequence. In the present case the normals actually derived from the computations for the Catalogue are: 32.2Aoo+ o.o A/u, = fooo o.o A739 + -oo37 + .009 -.0013 o .05 .27 .10 74 )8 Hydri 2.8 20 30.015 7i-S + 3.2208 .1480 +.360 + .7015-321 .04 .24 .IO 75 Br 26 7.0 20 32.538 65.2 + 3. 090 1 + .0068 + .OIO + .0028 o .08 .40 .20 76, Br 24 6.9 2O 42.082 70.4 + 3 .73o8+.2 3 i9 + .600 + .0081+ 4 .09 .39 .18 77 K Phcenicis 4.0 21 17.165 82.3 + 2.96i3-.0237 + .O22 + .0096 I .12 .70 .23 78 a Phoenicia 2-3 21 2O.55I 75-8 + 2.9746 .0228 + .O2 1 + .0175- 2 .10 .39 .16 79 Br 29 6.7 21 29.662 72.2 + 3.0758+. 0028 + .009 + .0048 o .07 .32 .14 80 Br 3 i 6.8 22 46.161 62.7 + 3.H72+.OI37 + .011 .0007 o -l8 .58 -33 to Br 3 2 5-4 22 50.072 56.5 + 3.i2i9+.oi27 + .OIO + .0081 o .13 .44 .27 82 Pi 74 5-3 22 5I.I3O 65-9 + 3. 2093 +.0342 + .024 + .0092 + I .12 .57 .28 83 77 Sculptoris S-o 22 58.223 83.6 + 2.9814 .0154 + .015 .0022 o .IO .64 .20 84 Br 3 3 6-5 23 0.896 59-i + 3.nio+.on8 + .010 + .0006 o .13 .51 .29 85 L 99 5-5 23 30.686 854 + 2.9655 -.0203 + .019 + .0099- I .12 .62 .20 86 Br 34 6-7 24 29.403 75-6 + 3.7600+. 1815 + 347 + .0954+38 .08 .51 .19 87 Pulk H 33 6.0 24 45.OOI 86.1 + 3. 3204+. 0615 + -056 + .0042 o .12 .84 .23 88 Br 3 6 7.8 24 47-363 67.0 + 3.0784 +.0024 + .009 + .0103 o .13 .48 .24 89 Br 3 5 5-3 24 50.638 70.6 + 3.I562 + .0207 + .014 + .0030 o .10 .39 .18 90 Br 3 8 6-3 24 56.112 76.4 + 3. 06 1 4 +.0009 + .OIO + .0005 o .03 .20 .07 9i Pi 91 5-4 25 22.703 81.6 + 3.0029-. 0095 + .OI2 .0026 o .08 .50 .16 92 L 109 6.6 25 34-753 90.4 + 2.9400 .0206 + .O2O .0006 o .12 .75 .19 93 Br 3 9 7.2 25 35-359 61.8 + 3.II09+.OII7 + .OIO .0027 o .13 .52 .28 94 L no 5-8 25 35-7 8 7 81.6 + 2.9140 .0270 + .O26 + .OIl6 2 .16 .90 .30 95 Br 3 7 6-3 25 39-9I7 72.6 + 3-4i23+.o844 + .095 + .0050+ I .09 .44 .l8 96 Groomb 75 5-9 26 12.507 93-9 + 3.2643 +.0464 + .036 -.0053- I .13 .57 .16 97 A Cassiopeia; m 4-9 26 15.137 70.4 + 3-2875 + -0497 + .040 + .0052+ I .08 .30 .14 98 Br 41 7-3 26 23.995 64.9 + 3.ii38+.oii8 + .OIO .0010 o 15 -57 -30 99 X Phoenicia S-o 26 35.587 83-3 + 2.9051 -.0274 + .026 + .0130 2 .14 .64 .22 100 /3 l Tucanae 4.6 o 26 57.745 75-8 + 2. 7 707 -.0443 + 055 + 0131- 3 .11 .50 .20 52 OS 5.

The unit of r is one century. We take as centennial /^,, 703^5 ; for p, + 399 "5 ; and for /*', S79'.'o, these being the instantaneous values assumed for 1875.

This is a celebrated binary system having a period of about 194 years according to See (Stellar Systems). See's orbit is here adopted in computing the relation of the separate stars to the center of gravity. Since the effective meridian-observations cover only about one-half of the orbital period, there is serious indetermination between the orbital and proper-motion. However, both of the stars have been well observed; and the comparatively equal brightness of components is prob- ably favorable to relatively small systematic errors of observation wherever the mean has been observed. Assuming the star which is now south -folio wing to be the principal star, the distance of the center of gravity from it in terms of the distance, p, between the two components is found to be as follows: From observations of /, R. A., 0.30 wt. i Decl., 0.56 wt. 2 From observations of y 2 R.

But since the brightness of the two components is nearly the same, and the difference in observed relative masses is smaller than the probable error properly attaching to that difference, the masses are assumed to be equal. On that basis the following table has been prepared, giving quantities which must be added to the catalogue-place to get the place of the principal star. Reversing the signs of the table and adding, we derive the predicted place of the companion star, at the present time north, preceding. Date. Aa. AS. Date. Aa. AS. Date. Aa.

The magnitudes are o^o and 1$, and the annual parallax may be taken as o"75. This is one of the most interesting stars in the sky on account of its large parallax, o"75, and its comparatively rapid orbital motion. In computing the place of the center of gravity, the orbit of Roberts (A.N., 133, 105) was adopted. This makes the period 81.185 years. The components are so widely separated that the observations of either should not be seriously affected in a systematic way by the presence of the other. In determining the position of the center of gravity, the two components are almost equally available. Following is a summary of results for the mass of the fainter compo- nent, that of the principal star being assumed as the unit : Mass 0.67 0.78 0.89 0.91 0.85 Wt. 8 55 14 70 Observations of fainter star, R.'

The period of this binary is 148.46 years according to Biesbroeck (A.N., 3989), and the mag- nitudes of the components are 4""8 and 6^7. Although the position angle of the companion had described less than 180 within the period of accurate measurements, the orbits recently computed are apparently entitled to greater weight than is usual under such circumstances. However, the relative motion of the components has been slowly accelerating up to the present time; and this is a condition that makes for uncertainty in prediction. Yet it is probably better to make some attempt to determine the relation of the masses of the two stars, and then refer the motion of the components to the resulting center of gravity than it would be to assume that the motion of either star is rectilinear. For the distance of the brighter star from the center of gravity, reckoned in terms of />, the distance between the two stars, we have: From right-ascension, .60 p wt. 2 From decl., .41 p wt. 5 Adopted, .47 p Accordingly, putting the mass of the brighter star as unity, that of the companion would be .87.

In particular, the fact that the companion reached apastron about 1870 and is now well on its way toward periastron, with accelerating motion, tends to make future prediction unsafe, in view of the absence of knowledge as to the approximate ele- ments of the orbit. The magnitudes, about 51*2 and 61 I 2, do not appear to be sufficiently unequal to render marked inequality of masses probable. The center of gravity is likely to be near the mean between the two stars. Adopting the mean, we should have: R. A. = is h o m 29?537.

This binary system has a period of 88.4 years according to See (Stellar Systems), whose orbit is adopted in determining the relation of the center of gravity of the two components, which are of magnitudes 4 M 3 and ^S. Both stars have been well observed; but it seemed well to reduce the observations of the fainter star to the places of the brighter star by means of the differences resulting from the adopted orbit. This done, it is found that the proportional part of the entire distance, p (reckoning from the brighter, toward the fainter star), at which the center of gravity is situated is, from meridian-observations of R. A., .48 .02 from meridian-observations of decl., .42 .03 The mean, .45 p, has been adopted as the most probable result, since the result from declina- tions, though having a larger probable error, is less likely to suffer from systematic errors due to the proximity of the two stars. Thus the mass of the fainter star in terms of that of the brighter is .82. It does not seem probable, in any case, that the fainter star has a larger mass than the brighter. The following table gives quantities which, added to the positions computed from the catalogue- place of the center of gravity, will give the predicted place of the principal star.

Although the micrometrical measures of this double star are numerous and accurate, the change in position angle is so small that it does not suffice for the computation of an orbit that is even fairly approximate. It might be assumed, however, with much plausibility, that the observed arc can be accurately represented by a parabola, following the precedent adopted with first orbits of comets. But in the present instance it has been found that not even this device would be of any service, since the direction of periastron is still indeterminate. Accordingly, as a last resort, and in order to provide more reliable means for predicting the positions of the two components, the combined effect of curvature of path and variation of proper-motion has been computed from the meridian-observations in each coordinate, assuming this effect to be proportional to the square of the time-interval, T, expressed in centuries, from the epoch 1875. We have for ^ : R. A. R. A. Decl. V) 61' Cygni (f 800389=) +'.'0460 -.0016! 6i 2 Cygni (.00129=) .0152 +.0204] Taking these as the basis of further computations, we may gain some idea of the relative masses of the component stars of this system in the following manner. Let the unit of mass be that of the brighter star, and a, the mass of the fainter star. Dr. Bergstrand determines the coefficient of the centennial term in r 2 for the differences in declination between the two stars to be +"0134; and the corresponding term in right-ascension, '.'0460. (Roy. Soc. Upsala, Ser. IV. Vol. I, No. 3.) These values are probably far more accurate than those which are derived from the meridian- observations, + "0220 and "0612 respectively. The ratio of Dr. Bergstrand's terms, 3.43, may be taken as a known quantity, therefore, so that if, for orbital effect alone, b denotes the coefficient of i 2 in declination-equations of the fainter star, then 3.43 b will be the corresponding coefficient for right-ascension. Further, let A/^, denote the centennial variation of the proper-motion upon a great circle, due to assumption of uniform rectilinear motion (see Introduction, as well as the note on Groombridge 1830, No. 3112), then we shall have the following equations: From 6I 1 R. A., 0.796 + 3.43 a b = + '.'0460 6i 2 R. A., 0.796 -p - 3.43 6 =- .0152 A 61 1 Decl., 0.605 _J-?_ i.ooa b = .0016 61 2 Decl., 0.605 + i. oo b = + .0204 The solution of these equations leads to the following values of the unknowns : Auo = + "0163 o = + 1.16 b = + '.'00841 ab = + '.'00975 Varying the assumptions adopted in the foregoing, values of a and ^ similar to these are 2 derived, and it is found that a value of a less than unity is not inconsistent with the data. One may rather confidently conclude that neither star has twice the mass of the other, and no great error will be committed if it be assumed that the masses are equal. The comparatively small differ- ence of magnitude of the two components is favorable to this assumption; and there is always a probability in such cases that the mass of the brighter star is not less than that of the fainter a probability which has been sustained in the computations for this Catalogue in every instance where the data were really adequate to a decision. Accordingly, the masses are here assumed to be equal. This being the case, one-half of the observed effect of perspective upon the proper motion of the center of gravity in a great circle will be found in the mean of the square-terms in right- ascension and declination respectively, already determined (A).

We may, therefore, adopt as the perspective effect observed in the meridian-observa- tions: A/UO = + "034, with a probable error of perhaps "020. A/XO may also be computed according to the formula of Seeliger (A.N., Bd. 154, s. 67. See also previous note on Groomb 1830). For this purpose let us assume: fi = s"2o; ir = '.'34; I = 62 km. The latter quantity is the result for motion in the line of sight derived at the Yerkes Observatory, in kind compliance with the author's request. This will give us A^, = + '022, in very fair agreement with that derived from meridian-observations. We may assume that this result is entitled to twice the weight of A^ from meridian-observations, and this leads to the value of A/* (the perspective effect) finally adopted: A^ = + "026 A/u = + "021 A^' = + "016 This means that the proper-motion of 61 Cygni is now increasing at about this rate ( + '.'026) per century, due to the perspective effect of approach upon the angular motion in a great circle of the projected uniform rectilinear motion of the point midway between the two stars. Combining this with the effect of orbital motion as determined by Dr. Bergstrand, on the assumption that one-half the effect is applicable to each star (and remembering that the effect on "secular variation" is twice this amount), we have: AM A/t' 61 1 Cygni, effect of perspective term + "0206 + "oi$8 61* Cygni, effect of orbital term + .0460 .0134 -I- '.'067 = + ^0056 + .002 61 2 Cygni, effect of perspective term + "0206 + "01 58 6i 2 Cygni, effect of orbital motion .0460 + .0134 .025 = '0022 + .029 It will be remembered that these quantities were determined directly from the meridian-observa- tions at the outset (equations A giving one-half these terms). We therefore have the following comparison between the values directly determined from the meridian-observations and those resulting from adjustment, as above, and adopted: Direct Adjusted 6I 1 Cygni. A^, = + '.'092 + '.'067 6I 1 Cygni. A/A' = .OO3 + .002 6i 2 Cygni. Ap, = .030 .025 6i 2 Cygni. Aii' = + .041 + .029 The agreement appears to be fairly satisfactory, and the secular variations and values of A/* and A/, as they would have otherwise appeared in the Catalogue, are corrected for perspective and orbital effects as herein adopted. Nos. 5832 and 5833. "Z 2922. For 1900 we have 5 M 9-6"7, 22", 185 for S 2922. There is a companion of B, 10" 28" 155. The two principal stars differ little in right-ascension. The meridian difference agrees badly with the result from micrometrical measures. In order to produce better agreement, the solution of the equations in right-ascension for No. 5832 (the fainter star, which is of 6^7) has been somewhat forced by the rejection of Br'y., Pi., Tay., and Paris tt . 278 PRELIMINARY GENERAL CATALOGUE OF STARS FOR 1 900 No. 6172. Br. 3198. 85 Pegasi. p 733. This is a binary with a period of about 25.7 years, according to Burnham, whose orbit is here adopted for special discussion of irregular proper-motion. The magnitudes of the components are 6"o and nfo respectively. The meridian-observations have a total weight of only 22.5 in R. A., and of 25.2 in declination, much less than the weights for any other binary treated in these notes. They give for the proportional distance of the center of gravity to the entire distance from the bright to the faint star: From right-ascensions 0.51 .16 From declinations 0.84 .20 Mean by weights 0.64 .13 This corresponds to a mass for the faint star of 1.8 the bright star having been taken as the unit. The aspect of these numbers lends plausibility to the hypothesis of greater mass for the fainter star. But the meridian-observations are not entirely inconsistent with the hypothesis of equality of mass, as may be supposed from the probable error. There is no other instance in which it has been pos- sible to demonstrate with a strong preponderance of probability that the fainter component of a binary star has the greater mass, while the strong natural inference must be in favor of greater mass for the brighter component, especially when the discrepancy in brightness is very great, as in the present instance. Accordingly, it is here assumed that the two masses are sensibly equal and that the center of gravity is halfway between the two stars. The Catalogue gives the position of the center of gravity. Adding to this position quantities derived from the following table, we have for the respective dates the positions of the brighter star. In like manner the position of the fainter star is obtained from this table after reversal of signs. Date. Aa. AS. Date. Aa.

SYSTEMATIC CORRECTIONS AND WEIGHTS. APPENDIX III. SYSTEMATIC CORRECTIONS AND WEIGHTS. The principal points concerning the formation of the systematic corrections and weights con- tained in this Appendix have been explained in the articles upon these subjects contained in Volume XXIII of the Astronomical Journal (Nos. 534, 536, 540, 541, 545, 549, and 550). There has been frequent occasion to allude to these quantities in the Introduction to the present volume. The Systematic Corrections herein contained are the result of an extension and thorough revision of the tables contained in Nos. 549 and 550 of the Astronomical Journal. The tables which follow give : Aa a . Systematic corrections in right-ascension that vary with the argument, a, are given in the first table. Bracketed with Aa a is sometimes given A'a, the coefficient of a term of correc- tion, A'oatgS. The distinction between these quantities is that Aa a is a correction com- posed of a constant in combination with a term periodic with right-ascension. At any particu- lar value of a it is constant for all declinations. This may be termed the equinox-correction. But in some cases there is associated with this a term which might be called the A'a. term. It is not only periodic in a, but at the same time varies with the declination more commonly as tg 8. Among other causes the term in A'a a may be attributed to an annual periodic error in determining the polar point of the instrument, so that, in reducing transits there is an out- standing error in them of the form, n tgS, with n having an annual period. In some cases there may be a sensible error of annual period in determination of collimation. This would produce an error in the transits of the approximate form, A'a. (tg tg * ), in which p i \ 2 2j the polar distance of a given star, and P is the mean polar distance of the clock stars employed. Aos. Systematic corrections in right-ascension that vary with the declination alone are given in the table next following that for Aa a . They may be due to irregularities of pivots, personal errors of the observers, errors of illumination, and a variety of causes. For convenience of in- terpolation, Aaj cos 8 is given in the tables for declinations higher than 80. Between +80 and 80 Aaj is given, as it is to be applied to observed right-ascension^ without multiplica- tion by cos 8. Aa M . At the foot of the pages giving Aaj are given the systematic corrections for Magnitude- equations, Aa M , of the several catalogues. The values of Aa M are probably more reliable for stars brighter than 7^0 than they are for fainter stars; but they should still be good approxi- mations in most cases down to 8o, or fainter. Values of Aa M marked * are not the result of observation, but are mean values computed from !oo69 (M 3.5). The total correction to be applied to the right-ascension found in the original catalogues of observation is : Ao = Aa a + Aaj + Aa M , where Aa. may be taken as Aa a + A'a a tg 8, when- ever the latter term becomes sensible. Corrections to the right-ascensions of the Zones of the Astronomische Gesellschaft follow in the next table. These corrections were derived with very great care and are based upon more than 2,900 quasi-standards. In determination of Aa M beyond seventh magnitude, much assistance was derived from the comparisons of the A. G. zones with each other and with Pulk 75, instituted by Dr. Auwers. (Ast. Nach., Vol. 161, Nos. 3842-3-4.) 279 is 280 PRELIMINARY GENERAL CATALOGUE OF STARS FOR 1 900 DECLINATIONS. AS.. Corrections in declinations that vary with the right-ascension alone as an argument are given next after the tables for A. G. zones right-ascension. Corrections of this form may be attributed to annual effects of temperature, etc., upon the instrument and its environment, neglected variation of latitude, and effect of faulty astronomical constants adopted in reduction from apparent place to epoch of catalogue, especially in earlier times. A8j. Systematic corrections in declination, with the argument declination, are found in the next table. In the case of Br 1755 the arguments 5 apart do not suffice. A special table of correc- tions, ASj, for Br 1755 appears under Remark (n) at the end of these tables. A8{ is easily accounted for through the effects of insufficiently corrected errors of graduation, flexure, refraction, etc. In some cases these curves have been analyzed and attributed to their probable sources (see, especially, Ast. Jour., Vol. XXIII, pp. 120-122, 126, 157-162, 210, etc.). Then follow corrections in declination of the Zone-Catalogues of the Astronomische Gesellschafl. The full systematic correction in declination is: AS = A8 a -f AS^. ^ ./i Next follow tables of weights that have been employed in the computations for this Catalogue. These were prepared from the probable errors of the residuals found in solution from the standard stars. For the catalogues of highest precision, only the principal standard stars were employed. In computing and successively revising the weights, particular attention was devoted to the pro- gressive relation of the weights to number of observations. It has been assumed that there is a probable error (b) that is not affected by the number of observations but is inherent in the instrument, observer, or environment; or what is much the same thing, this part of probable error may be considered to be due in part to the practical impossibility of determining all the minor peculiarities of curves of systematic correction. This amounts to the assumption that when a certain number of observations is reached in a series of observations, the probable error is no longer sensibly diminished by increase in the number of observations. Usually, the weaker the catalogue, the smaller this maximum number of observations will be. Combined with this is the ordinary probable error of observation (ei) which diminishes proportionally with :=, n being the number V n of observations. Obviously the probable error (e c ) of the catalogue-place will be: In the solution of such equations for determining eg and 1( it was customary to substitute for eo, in which r represents a trial ratio for fl, such as i, i 4, 5, 6 8. Then by o means of auxiliary tables that value of r is found which best harmonizes with the probable errors found for the residuals arranged in groups according to the number of observations. The adopted probable error of the unit of weight is '.30, repeatedly verified as the computation progressed. For convenience in the formation of normal equations for determination of Aoo and A/XO, etc., only the denominations of weight represented in the left-hand columns of these tables were used. This permits the formation of auxiliary tables in compact forms that greatly expedite the formation of the normal equations. When the zenith-distance of a star observed at a given observatory is more than 72, it has been customary in the computations for this Catalogue to multiply the weights for right-ascensions, as given in the tables, by certain factors presently to be given. In like manner factors are adopted for reducing the weights in declination, beginning with 65 of zenith distance. The adopted factors are: APPENDIX III 28l Z. D. FACTORS.

For many of the catalogues they are probably too large. For a few catalogues, indicated in the notes, special factors were employed. The body of the tables contains under the designation of each catalogue the number of observa- tions that corresponds to the weight found on the same line at the extreme left. It is scarcely necessary to say that these weights are relative only. They are based upon the assumption that the system of this Catalogue, in comparison with an individual catalogue of observation, is nearly absolute. Finally, come the Remarks, or Notes, which have been limited to the cases most in need of explanation. These are referred to in the tables by numerals inclosed in parentheses. 282 PRELIMINARY GENERAL CATALOGUE OF STARS FOR 1900 SYSTEMATIC CORRECTIONS IN RIGHT -ASCENSION.

(1) Bradley 1755. The term in Aa a , depending on tgS, applies north of declination +60, and it is necessarily very uncertain. (2) Pulkowa 1855. The observations upon which this Catalogue is based extend over a long period, and were chiefly made in broad zones. The mean Aa a applicable to the entire Catalogue is not far from +^007. Taking the Catalogue by zones, the following corrections have been determined, and may be substituted for the uniform correction +foo7. -20 tO o to +30 +30 to +60 +60 to Pole h o s +.006 s .000 s .004 s a + .007 +.012 tgS I + .009 .000 -.003 + .007 +.010 2 +.013 + .001 .001 + .007 +.010 3 + .016 + .001 +.003 + .007 +.010 4 +.018 + .OO2 + .009 + .007 +.011 5 + .020 + .004 +.017 + .007 +.010 6 + .020 + .006 + .O20 + .007 +.007 7 + .020 + .007 + .O2O + .007 + .004 8 + .019 + .009 + .016 + .007 .001 9 + .017 + .OII + .011 + .007 .005 10 + .OIS + .012 + .OO6 + .007 .009 ii + .OI2 + .013 + .003 + .007 -.013 12 + .008 + .014 + .005 +.007 -.015 "3 + .OOS + .OI4 + .OIO + .007 .017 14 + .OOI + .013 +.015 + .007 .018 IS .002 + .013 + .016 + .007 .019 16 .004 + .OI2 +.013 + .007 .020 17 -.006 + .010 +.008 + .007 .020 18 .006 + .008 + .001 + .007 .016 19 -.006 + .007 .004 + .007 .006 20 -.005 + .005 -.006 + .007 +.010 21 -.003 + .003 -.007 + .007 +.019 22 .OOI + .002 -.007 + .007 +.021 2 3 + .OO2 + .OOI .006 + .007 +.017 24 +.006 .OOO -.005 + .OO7 +.OI2 (3) Pulkowa 75. The second term multiplied by "k" is computed under the hypothesis of a systematic error in adopted collimation, varying with the time of year (or with the temperature). The form of such a correction would be : P (a sin o + b cos o) i-tg- wherein P is the polar distance, and the unit factor corresponds to 45 of declination. The result of computation gives: : ^017 sin .002 sin : { ?oi7sin o+foi3coso ], .002 sin 2 a + .006 cos 2 a J wherein k = APPENDIX III 339 The corrections computed from this formula seem to be fairly well supported in the individual zones up to + 60. North of the Pulkowa zenith the observations do not seem to require this correction. (4) Dorpat 1815. The corrections for this Catalogue are applicable to a manuscript-catalogue compiled from Struve's observations of 1814-15 (Part II, Volume I, of the Dorpat Observations). Essentially the compilation was effected as follows : Constant corrections were applied to the results for each night in 1815 on account of a revision of the places of the adopted fundamental stars. These, with adopted corrections, are : 3 S Capella +0.17 a Persei +0.21 Vega +0.17 8 Cassiop. +0.24 o Cygni + 0.18 e Urs. Maj. + 0.18 The mean constant correction might have been taken as +o?i8 without serious loss of accuracy. In the observations are given, for each star, coefficients of correction to be required on account of any future revision of the star-constants adopted in the reductions. The present manuscript- catalogue was formed with adopted Aberration = 2o'.'5o and Nutation = 9^224, the formula being : ?044 v+ ?oi2 o, v and a having the signification given in the Observations. The results for 1814 require systematic correction to reduce them to conformity with the revised right-ascensions for 1815, as described in the foregoing. The adopted value of this correction is in the sense (1815-1814): + o?i8 - ?044 v + [ + s .oig + ^031 sin (268^5 + o)] sec 8. The right-ascensions thus revised for the two years (half weight for 1814) constitute the manuscript- catalogue to which is applicable the corrections given in the table for Dpt. 15. (5) Bradley 1755. These corrections, A8 a , are mean values applicable respectively to stars south and north of the Greenwich zenith ; their determination is liable to material uncertainty; and it is quite possible that they could be proved not constant in all zenith-distances. (6) Dorpat 30. " Correctiones Ultimae" of the "Positiones Mediae" must first be applied to the declinations. (7) The tabular values of systematic correction in declination for Edinb 40 are divided into two series. Corrections A8{ under Edinb 4o a apply to Edinburgh observations until the end of 1840 and under 4o s to observations, 1841-1844; but the value of A8. for the two periods is assumed to be the same. The difference in A8 { may be partly due to difference of computed refractions in the two periods. (8) Radcl 45. The Catalogue declinations should first receive corrections taken from p. viii of the Introduction. A similar correction is required for Radcl. 60. (9) Cordoba 1875. There are decided systematic differences in both coordinates between the results, Clamp E. and Clamp W. ; also in declination between the results obtained in different posi- tions of the circle, the corrections in the table require additional special corrections for the separate years. (See Astr. Jour. (No. 550), Vol. XXIII.) Thus we have the following additional corrections, Aoj, for right-ascensions, Clamp E. For Clamp W. the opposite signs must be employed.

(10) Cape 80. The values of Aoj for Cape 80 recognize the division into zones. The cor- rections vary abruptly at 35, 45, 55, 65, and 75 of declination. For instance, from 30 to 35 the correction is to be interpolated between + ^034 and +?045, while between 35 and 40 the correction is to be interpolated between + ^014 and + ^024. Aa a and A8 S are not supposed sensibly to depend upon the division into zones. Since the zones were completed one after another, beginning at the South Pole in 1871 and ending in 1878, it might be assumed that there would be a material difference in the AS a that should apply to the respective zones, due to the differing amounts of variation of latitude in the correspond, ing years. Accordingly the values of AS,, under I have been determined as applicable to the ob- servations from the northernmost to 25; II, from 25 to 35; III, from 35 to 45; and IV, from 45 to the South Pole, it having been regarded as impracticable to determine a special correction for each zone southward from 45, owing to lack of material. (n) Bradley 1755. On account of the abrupt changes in the curve (attributed to error of graduation) it becomes necessary to give the correction AS for every degree.

The first column may be applied to all observations south of + 30. Weights between + 30 and + 40, and between + 40 and + 70 may be interpolated; and north of + 70 may be taken as at 70. 344 PRELIMINARY GENERAL CATALOGUE OF STARS FOR IpOO (18) Albany oo, Manuscript-catalogue. The weights in right-ascension, after a very careful discussion, were tabulated as follows: i obs. 2 obs. 3 obs. 4 obs. -2Ito 29 7 1-5 2.0 2-5 -30 .6 .0 2.O 2-5 31 .6 .0 2.0 2-S 32 .6 .0 1-5 2.0 33 5 .0 i-5 2.0 34 S .0 i-5 2.0 35 4 1.0 I.O 1-5 36 4 7 I.O I -5 37 3 .6 I.O I.O 38 3 S 7 I.O 39 .2 4 .6 7 40 IS 3 4 .6 4i .07 IS .2 3 These weights apply to observations in a single clamp, and were summed for the two clamps. Up to 4 observations, however, the table applies sufficiently well if the argument be total number of observations, irrespective of the number in each clamp. (ig) Lick 1900. These weights apply to the observations of Piazzi stars south of the Equator. For 16 observations of circumpolar stars the adopted weight is 5.0. (20) Pulk 45. From declinations + 55 to + 65, one half these weights in declination apply. Special Z. D. factors are employed as follows: At Decl. Multiply Weight by I + 10 IO -is .8 .6 -4 25 (21) Pulk 55. By far the most frequently occurring number of observations in this Catalogue is 4, and for this the weight in declination was computed to be .8. This weight was employed. (22) Pulk 65 and Pulk 85. For these two Catalogues the weights are modified in the same way. From declinations +55 to +65, the weights should be multiplied by .5; and as follows at the respective declinations : S Factor + 10 I.O o - s 0.7 0.6 10 -S -15 0.3 20 O.I (23) Wien-Ottakring 97. table. From 35 to 40 of declination the weight is one half that of the APPENDIX III 345 (24) Albany 1900. The following weights in declination, derived from special investigation, were adopted. I obs. 2 obs. 3 obs. 4 obs. 8 obs. 21 -5 0.9 i-3 i-5 3-5 -23 -4 0.8 1.2 1.4 3- ~ 2 5 0.4 0.8 I.I -3 3-o -27 -3S 0.7 I.O 1.2 3- -29 -3 0.6 0.9 1.2 2 -5 -31 -3 -5 0.8 I.I 2.0 -33 0.2 0.4 0.6 0.8 '5 -35 0.15 -3 -5 0.6 '5 -36 O.I 0.25 0.4 -5 i.i -37 O.I O.2 -3 0.4 0.8 -38 O.I 0.15 O.2 -3 0.6 -39 0.05 O.I O.2 -3 o-5 -40 0.05 O.I 0.15 O.2 0.4 The weights for each position were taken from this table, and the sum of the two weights, when observations were obtained in more than one of the four circle positions, AW, AE, BW, BE, con- stitutes the adopted catalogue-weight. In practice, the above table applies sufficiently well, with- out taking into account the separate positions, when the whole number of observations in the Catalogue is less than five. The last column under the caption "8 obs." refers to the numerous stars that were symmetrically observed twice in each of the four positions of the circles. (25) Cape oo. This includes the zone of reference stars for the astrographic chart, with mis- cellaneous observations outside the limits of the zone. The systematic corrections, and espe- cially the weights, are largely inferred from the corresponding quantities for Cape 06, since the material for an independent determination is very scanty.
