摘要
介绍了密集星场测光软件的研究背景和设计目标,描述了基于VC密集星场测光软件的实现,以及使用自己设计的程序对山东威海天文台1m望远镜观测的M39星团进行实际测量的实验结果。结果表明对于比较稀疏区域的亮星(约14mag)内部精度达到0.003mag,而对于较密集区域的暗星(约17mag)内部精度达到0.128mag。
This paper describes goals of the software which was designed for crowded-field stellar photometry,and discusses how to implement the program in Visual C＋＋ language.We conducted experiments of our procedure based on CCD images obtained with the 1 m telescope of the Weihai observatory of Shandong university.The results reveal that the internal precision is 0.003mag and 0.12mag for a bright star（～14mag） and a faint star（～17mag） respectively.
