Description:
   The positions in The Southern Reference Star Catalogue are the
   combined results of observations of all participants in the
   Southern Reference Star (SRS) observing campaign from 1961 to
   1973. Preliminary catalogs were compiled at both the U. S. Naval
   Observatory (Washington) and the Pulkova Observatory (Leningrad).
   The two compilations were compared, reconciled, and combined to
   render this catalog. The proper motions were culled from a number of
   sources and should not be regarded as part of the SRS observed
   catalog; they should not be used to extend the SRS system of
   positions very far from the mean epoch of the observations, which
   is about 1968. Two sets of positions and proper motions are given,
   referred to the Equator and equinox of B1950.0 and J2000.0,
   respectively. In addition to a serial number, in order of right ascension,
   the positions, and the proper motions, the catalog contains the
   original SRS number in the observing list, a code to indicate the
   source of the proper motions, the Durchmusterung number,
   magnitude, spectral type, the mean error, number of observations,
   and mean epoch for right ascension and for declination, the number
   of catalogs in each coordinate in the Washington and in the
   Leningrad compilations, and the differences (FK5-FK4) from the
   coefficients of the analytical representation by H. Schwan.
