Description:
   The Chinese Geodetic Stars Catalogue includes 4065 stars brighter
   than 6.6 mag north of declination -30 degrees. It contains 2226
   FK5 and FK4 supplemental stars and 1839 GC stars. The positions of 1391 GC
   stars were determined from observations with four Chinese
   instruments, reduced to the FK5 system and the equinox and equator of
   J2000. The mean epoch of observation is 1988.0. The mean precisions
   are 4 ms and 0.07" in right ascension and declination, respectively.
   The proper motions have been determined using the observing
   positions of 1391 GC stars and eight catalogs; the mean precisions are
   0.19"/cen. and 0.22"/cen. in right ascension and declination,
   respectively. The positions of the other GC stars are obtained from
   other catalogs. In addition to the positions and proper motions, the
   catalog contains the visual magnitude, spectral type, parallax,
   radial velocity, and Durchmusterung number for each star, the mean
   epoch for the observations in each coordinate and the mean error for
   each component of the position and proper motion.
