The mean precision of the residuals is ±0.046″ With these 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 precisisons are ±3.2 ms and ±0.061″in right ascension and declination respectively. The mean epoch is 1993.6.
