上海天文台1.56m反射望远镜新CCD相机的快门函数及线性

摘要

2002年9月12日曾对上海天文台1.56m反射望远镜新安装的Tek 2048×2048 CCD照相机的快门函数进行了测定,以供用户使用.还检验了此CCD系统的线性,证明它的线性在整个0～60000 adu范围内良好.%The shutter function of the new Tek 2048×2048 CCD camera was measured on 2002 September 12 for public use. The linearity of the CCD system was checked too. The nonlinearity is less than 2% for the whole intensity range up to about 60000 adu (gain = 2.4 e/adu).
