First catalogue of stars with photoelectric astrolabe in San Juan

Abstract

On the basis of data observed in San Juan of Argentina with the photoelectric astrolabe mark II (PA II) of Beijing Astronomical Observatory from Feb. 23, 1992 to Feb. 28, 1995, residuals of 7200 stars are reduced from about 230000 observations of stars. The mean precision of the residuals is ± 0:046. Using the data, the first catalogue of stars (CPASJ1) has been compiled. There are 2980 stars in this catalogue, including 989 FK5/FK4 Supp stars, 658 FK5 Ext stars, 387 SRS stars, 687 CAMC4 stars, 192 GC stars, and 72 Hipparcos stars. The mean precisions are ±3.2 ms and ± 0:061 in right ascension and declination, respectively. The magnitudes of stars are from 2.0 to 11.3. The declinations are from to -3° to -60°. The mean epoch is 1993.6. Finally, systematic corrections of (CPASJ1-FK5) are given.
