DNTBR THE SUPEHINTENDENCE OP THE EEV. ROBERT MAIN, MA., RADCLIFFE OBSEKVEE. PUBLISHED BY ORDER OP THE RADCLIFFE TRUSTEES. OXFORD: JAMES PARKER AND CO. 1870. INTEODUCTION. The present Catalogue of Stars, entitled tlie Second RadcUffe Cata- logue, contains the results of all the meridional Star-Observations which were made at the Radeliffe Observatory from the year 1 854 to the year 1861, both inclusive. During the year 1861, the Carrington Transit-Circle was established at the Observatory, and the use of the Meridian Circle by Jones, and of the Transit Instrument, was totally discontinued at the end of that year. It was desirable, therefore, to coUect the results of the observations made with those instruments, and to compile a catalogue of stars which should embody them in a definitive form. The formation of the Catalogue was commenced three or four years ago, but the heavy pressure of business prevented much progress from being made in it till within the last two years, during which time it has been completed and printed. The whole of the work connected with it has been performed by myself and Mr. Lufi", without the aid of any extra computers. I will now describe the processes which have been used in the com- pilation of the Catalogue, taking the columns of the printed tables in order. Column I gives the ordinal numbers of reference, and requires no explanation. Column 2 gives the magnitude of each star observed. The magni- tudes to which no asterisks are affixed are deduced from observation, the number of estimations being given in column 3. In explanation of the fractions which occur in the latter column, it may be stated that the estimation is allowed to have only half weight when a query has been put against it in the note-book of the observer. The magni- tudes to which asterisks are affixed are not observed magnitudes, but are taken either from Argelander, or from the Catalogue of the British Association, or other good authority. b Vl SECOND EADCLIFFE CATALOGUE OF STABS. Column 4 contains the names of the stars; and, in assigning the designations, they are made as much as possible to harmonize with those of the Greenwich Catalogue of aoaa Stars for i860, the order of preference being identical (or essentially so) with that given at page {x} of the Introduction to that work. One obvious advantage of this identity of nomenclature is the facility for comparison with the Greenwich Catalogue, the epoch of the two Catalogues being the same, namely i860. Column 5 contains the definitive Right Ascension for each star, obtained by combination of the observations made in the different years, giving as usual weights proportional to the number of observations. The Right Ascensions are brought up to the epoch i860 by means of the precessions, secular variations, and proper motions in columns 8, 9, and 10, the latter being (when un- bracketed) those found in my own papers on Proper Motion and that of Mr. Stone*. I have rejected in general the proper motions given in the Catalogue of the British Association, as un- trustworthy. The proper motions of a few stars, not given in the papers referred to, yet too considerable to be neglected, are included in brackets, and the greater number of them have been used in bringing up the stars' Right Ascensions to 1 860. Since, however, it was partly the object of Mr. Johnson in his list of stars, from which this Catalogue has been formed, to include all which he could find having conspicuous proper motions as well as other interesting pecu- liarities, I shall feel it my duty, as soon as I have leisure, to make suitable comparisons of all the stars with ancient Catalogues for the determination of their proper motions, and to pubhsh a list of those which require any alteration in their assigned positions through neglect of it. The Right Ascensions set down are not those which result imme- diately from the combination of the separate observations, but they are affected by the corrections necessary to reduce them to the equinox assumed in the Greenwich Catalogue. The epochs of the two Cata- logues being the same, it was comparatively easy to make the com- parison for all the stars common to the two Catalogues which have been observed a sufficient number of times (two observations at least in both Catalogues being in general the lowest number admitted) . The following table gives the result of the comparison, the number of stars compared being 453. * These papers are in vols, xix, xxviii, and xxxiii of the Memoirs of the Eoyal Astronomical Society.

Since then, as it is stated in that Introduction (p. iv), the equinox used depends fundamentally upon that used in the list of stars given in the Nautical Almanac for 1840, it is plainly desirable to make a comparison between the Right Ascension of the latter and 0^ the Greenwich Catalogue for the same epoch, namely the Catalogue of 1439 stars. This comparison is exhibited in the following table, which requires no explanation, as the numbers are taken out without alteration from the Nautical Almanac and the Greenwich Catalogue. ■viu SECOND BADCLIFFE CATALOGUE OF STABS. star.

IX An inspection of the results of this table, and a comparison with the table of excesses of the Greenwich above the Oxford Catalogues for 1845 and i860, will shew that it gives a satisfactory explanation of those excesses. The differences between the Nautical Almanac and the Greenwich Catalogue are on the whole larger, but there is the same relative diminution near the vernal equinox, and a general similarity which leaves no doubt of the origin of the discrepancies in the Radcliffe Catalogue. I have therefore thought it desirable to reduce all the results to the Greenwich equinox, by the application of the differences given under the different hours of Right Ascension as obtained by comparison with the Greenwich Catalogue for i860. Column 6 gives the mean of the epochs of observation in R.A. for the different years, and is formed by taking the means (with due regard to the number of observations) of the year and fraction of the year given for each star in the special catalogue for each year. Columns 7 and 8 give the geometrical precessions and secular vari- ations in R.A., and are those which would be found by the use of Peters' values of the constants. For precession, the formula for com- putation is, for epoch i860, 3-0720 + 15-3370 X Sin. E.A. Cot. N.P.D. = 3'0720 + I '3370 X Sin. o Cot. A (with the ordinary notation.) In practice I have avoided unnecessary labour in the computation of the precessions, first, by taking the precessions (and secular variations likewise) from the Greenwich Catalogue for all stars found in that Catalogue ; and secondly, by taking them, with suitable corrections, from the Catalogue of the British Association, for all stars not near the pole. For stars not found in either of these, the precessions and secular variations have been computed by myself. The constants m and n, (used in the B.A.C.) are those of Bessel, and, in my paper on Proper Motions {Memoirs of the Royal Astronomical Society, vol. xix.), there wiU be found formulae for reducing to those of Peters. The following table will give the corrections necessary to be applied to the precessions of the B.A.C. SECOND RADCLIPFE CATALOGUE OF STARS.

The precessions in N.P.D. need no correction. By applying then the secular variations of precession, the B.A.C. may be used for all stars not very near the pole contained in that work. The secular variation (independently of the variations of m and n) in R.A. has been computed where necessary from the following formula (jo and j5' being the precessions in R.A. and N.P.D.) Sec. var. in E.A. = — o"-O0O4848 X pp' Cot A +o'oooo323 x p'^ tan o Cosec.^A; and, for the terms dependent on the variations of m and n, by a process which is sufficiently obvious, from the formula + O»-00321 — 0»-000429 X j5. The latter formula, for convenience of use, I have tabulated, and I print it in this place because it may be useful to other astronomers. INTRODUCTION.

The latter are included in brackets. Column II gives the concluded North Polar Distances of all the stars observed, the means of the results for the different years being taken as in the case of Right Ascension. It may be mentioned that Mr. Johnson had compiled a catalogue from the results of 1854, 1855, and 1856, and included in it vol. xvii for 1856 of the EadcUffe XU SECOND RADCLIFFE CATALOGUE OF STARS. Obsei-vations. As the reductions appeared to have been made with great care, this Catalogue has been used instead of the partial catalogues for the years 1854, 1855, and 1856, and the N.P.D.'s are affected with a correction for the discordance 9f direct and reflexion results deduced by- Mr. Johnson in the fifteenth volume of the Observations. The obser- vations for 1868 were finally discussed under my own superintendence, and the same corrections are applied, but it was not observed till a portion of the present Catalogue (to 9^*" R.A. nearly) had been printed, that, in the results for N.P.D. for the year 1867, the correction was not applied. The corrections necessary to be applied in consequence of this error will be found at the end of the Introduction. As the North Polar Distances of the Radcliffe Observations ob- served with Jones's Meridian Circle have been discussed by foreign astronomers and have been found to exhibit a law of errors which deserves investigation, I have thought it worth while to make an elaborate comparison with the Greenwich Catalogue for i860. This has been a very laborious undertaking, as it was necessary to arrange the stars common- to the two Catalogues (very nearly 600 in number) in order of North Polar Distance. The results have, however, proved to be sufficiently valuable and interesting to warrant the time and labour bestowed upon the work, and I will proceed to give an abstract of them. The means of the excesses of the Greenwich North Polar Distances above the Oxford will be found in the following table, the stars having first been arranged in order of Polar Distance, and divided into groups varying from 5° to 8° in breadth.

The periodicity of the errors (assuming the difference between the Greenwich and Oxford results to be due to errors in the latter) is very obvious, butj before discussing it, it is necessary to bear in mind that different refraction-constants have been used at the two Observatories. At Greenwich BesseFs constant, used in the Tabula RegiomontaneB, is employed, while at Oxford this constant has been reduced in the ratio of I : o'9967, or is nearly that of the Fundamenta. I will therefore discuss the errors on two suppositions, namely, first, as they stand, or as obtained by the use of the diminished constant ; and secondly, as they would stand if Bessel's constant had been used undiminished. Now a single glance at the table exhibiting the errors will shew e XIV SECOND RADCLIFFE CATALOGUE OF STABS. that they follow a very simple law, and they could be represented by a formula of this shape, a + 6Sin4N.P.D. For example, the errors vanish after passing from positive to nega,tive near the pole, and again between the 14th and 15th group, or at an interval of 90°; and the -maximum negative is attained when the N.P.D. is about 18° and the maximum positive when it is about 6^°, or at an interval of nearly 45°. Assuming then this law, the following table will give the elements for the solution of the equations for determining the constants a and 6, on the two suppositions which have been named, weights being assigned very nearly in proportion to the number of observations. 05: 3 P 1 2, Excess of Greenwich uncor- rected for Refraction.

With regard to the precessions, since BesseFs value of n (used in the B.A.C.) is — ao"*0538, and that of Peters is %o"-o^^6, the precessions in the B.A.C. (when reduced to i860) may be used without scruple, and, as they are a function of the right ascension only, they may be readily interpolated for stars not found in that work. The expression for the secular variation of precession (independently of the variation of n) is + 0-I4685 X li Sin E.A. (where the constant is 100 X 15 »j Sin i".) The part depending on the variation of n is represented by - a« Cos E.A. = + 0-00863 Cos E.A. ; and the following table will make its application easy. INTRODUCTION.

The general compilation of the Catalogue and the combination of the observations were performed by Mr. Luif with his usual skill and zeal. The whole work has been one of great labour, and I trust that the Catalogue will be acceptable to astronomers, and not be considered inferior to its larger predecessor in accuracy and general usefulness.
