本文的目的是提出一种方法来自我校准的光谱能量分布（SED）的基础上，一个调查的SED库的拟合观测到的光谱光度测量的对象。为了便于说明，我们采用Vilnius和古恩&斯特赖克SED库。自校准技术可以提高在不完全光度条件下进行的观测的质量。用于光度测定的通带越多，结果越好。该技术已应用于BATC 15通带CCD巡天。
The purpose of this paper is to present a method to self‐calibrate the spectral energy distribution (SED) of objects in a survey based on the fitting of a SED library to observed multicolor photometry. We adopt, for illustrative purposes, the Vilnius and Gunn & Stryker SED libraries. The self‐calibration technique can improve the quality of observations which are not taken under perfectly photometric conditions. The more passbands used for the photometry, the better the results. This technique has been applied to the BATC 15 passband CCD survey.
