IX On comparing the entries in columns 3, 4, 5, and 6 of this table with the mean contained in column 7, the discordances between right ascension observations made in the four conditions of the instrument mav be summarised as follows : TABLE II.

If we similarly compare the mean results with those of Newcomb's Catalogue, the comparison may be summarised as follows : TABLE III.

If, however, we arrange the stars in order of declination, we derive the following summary of results : TABLE IV. Comparison of Cape Ledgers with Newcomb's Catalogue in order of Declination.

XI but which increases southwards at the rate of about s '001 per degree of declination. The effects of such an error on the periodic errors in R.A. will, however, be insignificant, as the clock stars in the higher declinations are fairly uniformly distributed in right ascension, as is evidenced by the following table, showing the distribution of clock stars in declination.

In so far, however, as the errors of the original system depend on the right ascension they will only be partially smoothed out, the more wide-spread features being reproduced almost in their entirety. To examine such errors recourse must be had to additional observations which have not otherwise been included in the formation of the Catalogue. Discussion of Daylight Observations of Clock Stars. In addition to the observations made in the night watches directly for the pur- poses of the Catalogue, regular observations of the Sun and inferior planets have been made by day. These have always been accompanied by observations of bright stars for the determination of clock error. The stars used are for the most part con- tained in the above clock star list, but include also the following additional stars, the places quoted being derived from the Cape Ledgers in the same manner as for the former stars.

In order, however, to subject it to a closer analysis it has been assumed that it is primarily due to a periodic error in the clock-star system used, which may be expressed analytically by the formula Aa = A l cos a + K-L sin a+A, 2 cos 2a+5 2 sin 2a. INTRODUCTION. xix This has further been regarded as possibly associated with a diurnal periodicity, either due to different habits of the observers in daylight observing as contrasted with night observing, or to a diurnal change in the conditions of the transit circle or a diurnal period in the clock rate. Thus each of the differences Day Night has been equated to an expression of the form K+A^cosa^ cos a 2 ) + .B 1 (sin ctj sin a. 2 )+^ 2 (cos 2a i cos 2a.,) + 5.,(sin zaj sin 2a.,), where aj denotes the K.A. of the day star and'a 2 the mean R.A. of the night stars on which the comparison depends. The quantities a lt a 2 are given under the headings S.T. (sidereal time) of Day Observations and Mean S.T. of Night Observa- tions in columns 3 and 4 of Table VII. While the quantities A 1} B lt A 2 , B z have been regarded as constant throughout the series of observations, the quantity K has been considered as possibly variable with the observer or the method of observing. We give in Table VIII. partial normal equations obtained by grouping the observations according to the observer and the year of observation and combining the separate equations with equal weight.

If we give equal weight to the determinations in each of the four years involved, the mean result derived from all the observations amounts only to +0' S 0023 for the mean observer. It follows that there can be little or no danger of the determinations of the periodic errors in JR. A. being vitiated by periodic errors due to diurnal changes in the instrument or the clock. INTRODUCTION. xxv The quantities contained in the two final columns of Table X. have been adopted as definitive, and, together with the finally derived values of AI, S lt A z , B 2 , have been substituted in the original equations of condition. From the sum of the squares of the residuals thus formed the probable accidental error corresponding to weight unity has been derived as db0 8 '031 ; whence, with the weights derived, the probable accidental errors of A,, B,, A t , B t , amount to S '0009, 0-0008, 8 '0011, S '0012. The agreement between the derived values of these same quantities from the groups of observations, either arranged according to time or according to the observers, does not confirm this high estimate of the precision, doubtless on account of cumulative systematic errors. To obtain a more reliable estimate of the probable errors, both accidental and systematic, of the results, the derived values have been substituted in the partial normals (Table VIII.) ; the residuals are given in the last column but one of this Table. Now it is evident that if any one of these partial normals be written in the symbolical form )x + (ab)y+(a<;)z+ .... =(an), where each of the quantities n is of weight unity, the square of the mean error of the absolute term will be (aa)e 2 , e denoting the mean error corresponding to unit weight. Hence we may reduce the equations to equal weight unity by multiplying by the factor \l J(aa). The final column in Table VIII. gives the residuals from the equations thus reduced. Now if the quantities thus obtained represented true errors, instead of residual phenomena, since each has the same weight unity, the mean of their squares would give a determination of the square of the mean error for unit weight, but in that the derived phenomena depend on the equations themselves, we may anticipate that the average residual will be less than the average error. On the other hand, the sum of the squares of the residuals will exceed that which would be derived from a least square combination of the partial normal equations re- garded as equations of condition. But, according to the usual conventions of least squares, if 2i> 2 denote the sum of the squares of the residuals, m the number of equations, and n the number of unknown quantities, Hence if v' denote residuals from a solution other than a least square solution, Applying this formula to the present case, a superior limit to the probable error corresponding to unit weight is found to be S '043 and the corresponding probable errors of A lt B do not exceed 8 '0013, those of A^ B z , 8 '0018.

On the basis of this determination the probable error, inclusive of residual systematic error, as well as purely accidental error of the quantity A l cos a+5j sin a-\-A cos 2a-\-B 2 sin 2a, amounts at a maximum in any right ascension to db0 8 '0022. As regards the actual values derived for the coefficients A lt lt A 2 , B z , confirmation has been sought from comparison with approximately simultaneous series of observations made in other observatories, with results that support the values here derived (see Monthly Notices, January 1913). For the purposes of the present Catalogue it has, however, been thought desirable, in order to maintain its fundamental character, to avoid the introduction of extraneous evidence.

These may be in part accounted for by residual division-errors and by the variations in flexure under the different conditions.

To the difference II-I a correction on account of variation in the flexure co- efficient, amounting to 0"'14 sin , where denotes the zenith distance, has been applied, and the results then smoothed in like manner. Denoting the semi-differences ^(II-I) by A, and the semi-difference |(E-W) by BI or B n , the following table gives the smoothed values for these quantities which have been used : Table of Systematic Discordances.

The separate observations have been reduced with the instantaneous nadir reading in combination with an assumed mean latitude and Albrecht's values for the periodic fluctuations of latitude, except in the case of close circumpolar stars observed during 1911. The latter have been separately discussed (Cape Annals, xi., part 3), the fluctuations of latitude being derived in this case from the observations themselves. From this discussion it appears that the latitude corrections required to reconcile the above-pole and below-pole observations at the Cape are less than those derived from observations at the International Latitude Stations by 0"'18 in the mean, or, in other words, the adopted mean latitude used in the reductions requires to be diminished by 0"'18. In deriving this value, however, no account was taken of the instrumental flexure. For the year in question the mean value of the flexure coefficient was + 0"'34, giving as the amount of flexure in the neighbourhood of the pole 0"'28, in the sense in which it is to be applied to declina- tion observations at upper culmination. Taking A 8 = A <+/ sin for stars above pole A 8 = A f sin f for stars below pole where A<5 denotes the correction required to the declinations of the Ledgers, A< the correction to the adopted latitude, and/ the flexure coefficient, the above determinations give /sin = o"'28 whence A< = +o"-io. The observations during this year were all made with the transit circle in Position I. Now we have already seen that there are small systematic discordances between results obtained in Positions I. and II., amounting at the pole to +0"'14, in the sense I-II. We may refer the latitude to the mean system --(! + II) by adding half this difference. Thus the correction to the adopted latitude, suitable for application to determina- tions made by symmetrical observations in the two positions, as derived from the observations of circumpolars in the year 1911, is XXX CAPE FUNDAMENTAL CATALOGUE, 1900. When the instrument was used in Position I., in the years 1906-10, direct determinations of flexure indicate that the mean flexure coefficient was sensibly constant. Hence for these years observations of the same star, made in this position of the instrument, have been treated as homogeneous and combined into a single mean. The determinations above and below pole have been thus separately grouped. The mean differences between the results for each star are contained in the following table : TABLE XIII.

The weights are derived from the formula mn m + n' where m, n denote the number of observations made respectively at upper and lower culminations. Taking the means with these weights, we find, from Clamp E, AS (above below) = + o" 8 1 , weight 217; and, from Clamp W, AS (above below) = +o"'2i, weight 192. INTRODUCTION. xxxi The difference between these results is in conformity with the discordances already found between declination determinations with reversed clamps. If we had previously applied the corrections represented by A, B l above, the above determinations would have been increased respectively by the values of 2(ABj) at the pole. The result- ing corrections to the declinations on account of the combined effects of latitude and flexure would then be o"'40 (A+Et) = o"'i6 for Clomp E. o"-io (A .6,) = o"'20 for, Clamp W. These results are in reasonably close agreement. Subtracting the part 0"'28 due to flexure alone, we derive from the mean of the two latitude corrections referred to the mean system [^(I + II), ^(E The flexure determinations made in Position II. during the years 1905-10 show variations from year to year. Consequently for this position of the instrument a separate investigation on similar lines has been made for each year. Table XIV. gives the results derived from separate stars. TABLE XIV.

The mean latitude of the transit-circle, as derived with the Pulkowa refraction constant, is therefore -33 56' 2 "'36. Instead of utilising the mean value of the latitude correction in order to reduce the whole series of observations to a homogeneous system, it has been thought preferable to apply to each homogeneous group of observations the values of the corrections derived solely from the observations contained within the group.

FORMATION OF DEFINITIVE CATALOGUE PLACES. The systematic periodic corrections to the right ascensions derived in I. (p. xxvi) and the corrections to the declinations derived in II. (p. xxxiv) were applied to the Ledger places, and separate means were first formed for the groups of observations in each of the four conditions I. E., 1. W., II. E., II. W. These separate means were then combined into a single mean, with weights dependent on the number of observations in each group, in accordance with the following scheme of weights : No. of Observations. Combining Weight. i -3 I 4-7 i 8-10 i 10+ 2 In the case of those stars which are contained in Newcomb's Catalogue, the observations in the Ledgers have been referred to the mean epoch J.900'0 by the application of Newcomb's proper motions. In forming the final Catalogue positions, the proper motions thus introduced have been removed. In the case of the double stars Sirius, Procyon, and a Centauri, the reductions to epoch include also the reductions from the bright (or observed) component to the centre of gravity of the system. The corrections thus introduced have been removed in like manner, so that the places quoted in the Catalogue represent the position of the actual object observed referred to the equinox 1900 - 0, but to the mean epoch of observation. The, right ascensions of the close circumpolars observed during 1911 have been adopted without further modification from the discussion of the observations contained in Cape Annals, vol. xi., part iii The declinations of these same stars have been derived from the combination of the results therein with additional observations in other years. These additional observations have first received corrections, as indicated in the last section, and the combination has then been effected by regarding all the observations as of equal weight, i.e. the means from the various groups have been combined with weights simply proportional to the number of observations in each. The entries in the separate columns of the Catalogue have the following significance : Column 1. " No." The rotation number. * and t attached to a number indicate a footnote, t being used in the case of double stars. Column 2. " Mag." The magnitude taken from Boss's Catalogue or the Harvard Publications, or a few, marked with an asterisk, from recent Cape Observations. Column 3. " Name." For Bradley stars the name in Auwers' Bradley has been adopted, except in a few cases mentioned in footnotes ; for stars south of declination 23, the C.G.A. has been followed, with the exceptions used by Auwers in vol. xlvii. of xxxvi CAPE FUNDAMENTAL CATALOGUE, 1900. the Monthly Notices. The names of the stars z Octantis, A Octantis, have been re- tained in accordance with the usage in previous Cape Catalogues. For stars otherwise unnamed, a Catalogue number is given in the following order of preference : Bradley ; Mayer; Lacaille ; Piazzi ; Lalande ; Brisbane; Catalogo General Argentina (C.G.A) ; Cape 1880 ; Gilliss's Circumpolar Zones ; Bonn Durchmusterung. m,pr, seq, br in this column signify mass, preceding component, following component, or bright component. Columns 4 and 9. "Mean E.A. 1900'0 " and " Mean Dec. 1900'0" respectively. The mean right ascension and declination derived from the observations made for the purposes of this Catalogue, and combined according to the methods described above. They are referred to the mean epoch of observation, but to the equinox of 1900'0. The third decimal figure is omitted from the Mean R.A. of Polar stars observed in 1911 only. The R.A. is supplied to the nearest second for stars not observed in this element. Columns 5 and 10. "/xAE." The quantities tabulated in these columns are the corrections on account of proper motion to be applied to the entries in the columns immediately preceding in order to refer the latter to the epoch as well as the equinox of 1900'0. They depend on the values of the proper motions in columns 8 and 13. Columns 6 and 11. "Annual Variation 1900'0." The annual changes in right ascension and declination due to the combined effects of precession and proper motion. Where no entry is contained in the columns immediately preceding, the quantities in these columns represent the annual precession computed from the formulae tan 8 sin a, I p s = n cos a I where, in accordance with Newcomb's values for the precessional motion, m= n= Columns 7 and 12. "Sec. Var. 1900'0." The quantities given in these columns are in general the centennial variations of the annual variations due to the combined effect of the motions of the pole and equinox and the " proper motion " of the star. If we denote by a, S the true co-ordinates of a star referred to the mean equator and equinox of epoch t, and suppose that t is expressed in terms of the tropical year as unit, the quantities involved are the values for 1900 of the expressions Let us suppose that the " proper motion " of the star consists of a motion with uniform velocity along a great circle. In the annexed diagram, let S denote the star's position at time t, S' its position at time t + At, and C the pole of the great circle SS'. Further let P, Y represent the mean pole and equinox of the epoch t. INTRODUCTION. Let p denote the amount of the annual proper motion and reference to the pole of epoch t. Then in the diagram below xxxv its position angle with = --x The variations in a , S due to the processional motions of P , Y are given by the formulae, (A) above, where however m and n should not be regarded as strictly constant but as functions slightly variable with the time t. these values at epoch 1900 +t are In accordance with Newcomb's determinations m= n= If fJ-d > Ms denote the " proper motions " of the star, in E.A. and declination respectively, referred to the equator and equinox of epoch t\ ^,/ua are the parts of the complete expressions for -^ , -37 which cannot be attributed to precession, i.e. d8 The changes thus represented by /jt ,/x s in the interval A result solely in the trans- ference of the star from the point S to the point *S", irrespective of any motion which may be attributed to the" points JP,Y. Hence if we draw the perpendicular S'N on PS, we have S'N = fJLa^-t COS 8 xxxviii CAPE FUNDAMENTAL CATALOGUE, 1900.
