在拥挤的领域中进行恒星测光的难度很大，目前正在使用一些不同的计算机程序，用于从二维数字图像中获得测光信息。本文描述了一个这样的程序，DAOPHOT，它是由Dominion天体物理天文台编写并继续开发的。重点放在寻求混合恒星图像的准确光度测量时出现的各种哲学和技术复杂性，以及DAOPHOT试图处理这些复杂性的数学算法，而不是编码的细节。文中提到了DAOPHOT与其他类似程序的一些相似或不同之处，并讨论了当前程序的已知缺点以及未来改进的可能性。
The difficult art of stellar photometry in crowded fields is currently undergoing a surge of popularity, and a number of different computer programs for deriving photometric information from two-dimensional digital images are currently in use. This paper describes one such program, DAOPHOT, which was written and continues to be developed at the Dominion Astrophysical Observatory. Emphasis is placed on the various types of philosophical and technical complications which arise when accurate photometry is sought for blended stellar images, and on the mathematical algorithms with which DAOPHOT attempts to deal with these complications, rather than on details of the coding. Some ways in which DAOPHOT resembles or differs from other similar programs are mentioned, and a discussion is presented of known shortcomings of the current program as well as possibilities for future improvement.
