摘要
测定了1．56m望远镜CCD照相机系统的消光系数和转换系数，消光系数k＇和k＂列在表1和表2，从观测星等到标准星等的转换系数列在表3。结果表明1．56m望远镜CCD测光系数做绝对测光是有困难的，最好是做相对测光。
The extinction and transformation coefficients for CCD camera system of 1. 56m telescope of Shanghai Observatory have been determined. The extinction coefficients kI and kn are listed in table 1 and table 2. The transformation coefficients between observing magnitudes and standard magnitudes are listed in table 3. It shows that it is difficult for doing absolute photometry with the 1. 56m CCD photometric system. It is suitable for relative pho-tometry.
