摘要
本文对CCD图象预处理中的本底场、平场、带干涉条纹的天光背景等图象的获得及处理进行了讨论,并介绍了获得背景的中值法。
It is discussed in this paper how to make and process a 'bias', 'flat' and a 'sky background with fringe' in the preliminary processing of CCD observations. In addition, the 'median' method of getting a standard background image is introduced in some detail.
