摘要:

本文提出了一种改进的宽视场图像天体测量归算算法。该算法是基于普通最小二乘法(OLS)和统计学生t-准则的迭代使用。该算法提供了最概率的约简模型的自动选择。这种方法可以消除几乎所有的系统误差所造成的现代大型望远镜的光学系统的缺陷。

英文摘要:

In this paper we presented the modified algorithm for astrometric reduction of the wide-field images. This algorithm is based on the iterative using of the method of ordinary least squares (OLS) and statistical Student t-criterion. The proposed algorithm provides the automatic selection of the most probabilistic reduction model. This approach allows eliminating almost all systematic errors that are caused by imperfections in the optical system of modern large telescopes.
