Scientific paper

On January 26, 2006, an area of the sky of 80 deg2 at α = 9h, δ= 20o (J2000.0) was observed with the 100/120cm Schmidt telescope at the Xuyi station of the Purple Mountain Observatory. Astrometric performance of the telescope is analyzed by this group of CCD observations. The results show that: (1) the CCD images suffer from complicated distortions, and a third order plate model is recommended for reductions; (2) there is no obvious magnitude equation for objects brighter than 16.5 mag, and (3) for this group of CCD images, the astrometric precision for objects brighter than 16.5 mag is better than 70 mas per coordinate when reduced against the UCAC2 catalog.
