Abstract:
Using the data observed in San Juan with the photoelectric Astrolabe
Mark II of the Beijing Astronomical Observatory from February, 1992
through March, 1997, the radio stars catalogue in San Juan (RSSJ95)
has been compiled. There are 69 radio stars in this catalogue. The
Positions of the radio stars are for the epoch of observation and the
equinox J2000.0 and a system close that of the system FK5. The mean
precisions are ±2.2ms and ±0.035" in right ascensions and
declinations, respectively. The magnitudes of stars are from 0.9 to
10.7. The declinations are from -2.5° to -60°. The mean epoch
is 1995.1. Finally, the comparison results with Hipparcos catalogue
and CAMC are given.
