| Abstract | 介绍一种利用大视场测光系统对观测天气质量进行评估的统计方法. 此方法可以给出大气透明度、背景天光、视宁度和观测极限星等等多种与天文观测有关的天气质量参数. 通过检验证明, 此方法可提供一个天气状况的实时监视方法, 对北京天文台施密特CCD测光系统以及制定观测计划和评估观测质量有重要意义. A statistical method based on wide field photometry is developed togive a quantitative evaluation of sky quality. The parameters used include the sky background brightness and transparency, theS/N and the limiting magnitude. Several tests have been used to checkthe reliability of the method. The paper shows that the methodprovides a real-time quantitative monitoring of the sky variation and so help optimize the usage of observing time of the BAO Schmidt CCDsystem. |
