| 摘 要： | 介绍了实现CCD整体平差的FORTRAN归算程序的详细流程,包括(a)数据收集、(b)预处理和(c)整体平差与结果输出共三个步骤,并给出了各步所调用的子程序名称及其功能说明。采用模拟数据对该程序进行了可靠性检验,并将该程序应用于4颗河外射电源的光学定位。结果表明, 由于利用整体平差方法参加归算的观测资料覆盖天区扩大,包含了较多的参考星,因而可以获得高于单底片归算的定位精度。

| Abstract: | A FORTRAN version realization of the block adjustment (BA) of overlapping CCD frames is developed. The flowchart is introduced including (a) data collection, (b) preprocessing, and (c) BA and object positioning. The subroutines and their functions are also demonstrated. The program package is tested by simulated data with/without the application of white noises. It is also preliminarily applied to the reduction of optical positions of four extragalactic radio sources. The results show that because of the increase in the sky coverage and number of reference stars, the precision of deducted positions is improved compared with single plate adjustment. |
