摘要
经在22GHz的指向校准,目前紫台13.7米望远镜的指向精度优于25″,能满足22GHz波段天文观测的要求。本文给出所采用的指向校准方法,及1989年10至12月期间指向校准观测的结果。
In the period of Oct.—Dec. 1989, a series of pointing observations has been done on the 13.7M radio telescope of Purple Mountain Obbservatory at 22GHz band. At present, the pointing accuracy of the telescope is better than 25', enough for the 22GHz radio astronomical observations. This paper describes the method of pointing calibration and the results of pointing observations.
