英文摘要	In this paper optical positions relative to UCAC1 for 22 counterparts of extragalactic radio sources in the southern hemisphere are presented. The internal accuracy of the positions is of the order of 0."060. With the help of astrometric calibration regions, choices of the centering method and the width of the subraster used for object centering are given based on the detailed analysis of the results of centers of stellar images in the CCD on the 1 m telescope at Yunnan Astronomical Observatory, and the choice of the suitable model for the reduction of CCD is also recommended. A comparison of our results with those of other authors is made.
