photom is a collection of programs designed to take raw, instrumental measurements of stellar brightness and convert them to calibrated magnitudes on some standard system. They were written as part of the TASS Mark IV pipeline, but may work on other datasets.
photom 是一个程序集合,用来接收原始的、由仪器测量的恒星亮度值,并将它们转换成某标准系统中的校准过的星等。它们作为TASS Mark IV流水线的一部分被开发,但也可以在其它数据库上工作。
