Taking the weighted means of the six groups we get the following numbers,
corresponding quantities from the Ten-Year Catalogue being added for comparison on
two methods. In columns marked (1.) the result is deduced by selecting actually the

same stars as those of the Five- Year Catalogue from the table on pages 46-54 of the
SO 11426. GREENWICH FIVE-YEAE CATALOGUE FOR 1890. c



14 GREENWICH FIVE-YEAR CATALOGUE OF FUNDAMENTAL STARS FOR 1890.

Introduction to the Ten- Year Catalogue ; in the columns marked (2.) the result for
the particular N.P.D. is inferred from the collected results on page 55 of that Introduc-
tion, except in the case of the first group.

The evidence, so tar as it goes, seems to show that the Systematic Errors of the
Five- Year Catalogue are nearly the same as those of the Ten- Year Catalogue,
especially in N.P.D.

FIVE-YEAR CATALOGUE



OF



258 FUNDAMENTAL STARS



FOR



1890-0



FROM OBSERVATIONS



MADE AT THE



ROYAL OBSERVATORY, GREENWICH,



1887 to 1891.



GKEENVICH FIVE-YEAR CATALOGUE FOB 1890.



NOTE.



STAR'S NAME.

The " Star's Name " adopted in this Catalogue is taken from one of the following authorities,
the order of preference beiiag the order of mention of the authority below :

1. Flamsteed's constellation No. and constellation, with Bayer's letter, taken from Baily's

edition of Flamsteed, or from the British Association Catalogue. When the description
in Baily's Flamsteed (B. F.) differs from that in the British Association Catalogue (B. A. C.)
the difference is mentioned in the Notes.

2. The No. in Bessel's Fundamenta Astronomies deduced from Bradley's observations,

referred to as " Bradley."

3. The Hour and No. in Piazzi's Catalogue, edition 1814.

4. The No. in Groornbridge's Catalogue.



MAGNITUDE.

The magnitude is taken from the Harvard Photometry for stars contained in that work, and
for other stars (marked *) from the Bonn Durchmusterung. For the few remaining stars
(marked |) the authority for the magnitude is given in the Notes. The magnitude in the
Uranometria Nova Oxoniensis is given in the Notes for all cases in which it differs by more
than 0'2 magnitude from that in the Harvard Photometry.

The magnitudes of the components of double stars, taken from Struve's Mensurce Micrometricce
or other authority, are given in the Notes.

In the case of variable stars the limits of magnitude and the period given in the Notes are
taken from Mr. Chandler's Catalogue in the Astronomical Journal, Nos. 179, 180.



PROPER MOTIONS.

The proper motions are taken from Professor Auwers' "Neue Reduction der Bradleyschen
Beobachtungen " or his " Catalog der Fundamental Sterne " for stars contained in either of those
works. The authority for other proper motions is given in the Notes.

59. The magnitude given in H. P. is 2-4; in the Uranometria, Xoca Oxonic/isis 2-0. The limits of magnitude are 2- 2 and 2 7. Auwers found a
i6 d - period. Schonfeld a slight variation but no period, Chandler and Sawyer no fluctuation of light.
62. Authority for Proper Motion : Cape Catalogue 1880.
64. The magnitude given in H.P. iso-g. The limits of magnitude are I and 1-4; Argelander found period 196''-, Schonfeld thinks periodicity
questionable.
