摘要

我们讨论了为确定可见双星或多星的相对坐标（位置角θ和间隔ρ）而开发的软件。它是基于傅立叶变换在处理这些系统的CCD帧中的应用。目的是在尽可能大的范围内自动确定相对坐标。以这种方式，减少许多CCD帧所需的时间变得更短。对软件的功能和局限性进行了检查。此外，还考虑了改进的可能性。该软件已在2011年10月保加利亚罗镇2米望远镜获得的165颗双星或多星的CCD帧样本上进行了测试和检查。将结果与应用不同软件得到的相应结果进行了比较，发现一致性非常好。

Relative-coordinate determination for visual double stars by applying Fourier transforms

We discuss the software developed for the purpose of determining the relative coordinates (position angle θ and separation ρ) for visual double or multiple stars. It is based on application of Fourier transforms in treating CCD frames of these systems. The objective was to determine the relative coordinates automatically to an extent as large as possible. In this way the time needed for the reduction of many CCD frames becomes shorter. The capabilities and limitations of the software are examined. Besides, the possibility of improving is also considered. The software has been tested and checked on a sample consisting of CCD frames of 165 double or multiple stars obtained with the 2m telescope at NAO Rozhen in Bulgaria in October 2011. The results have been compared with the corresponding results obtained by applying different software and the agreement is found to be very good.
