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.
