摘要
利用1.56m望远镜圆顶平场和天空平场的资料，通过对各种滤光片得到的平场内各区域的统一计，研究了圆顶平场之间、天空平场之间以及天空平场和圆顶平场之间的差异。观测资料分析结果表明，圆顶平场之间相互一致，天空平场之间也相互一致。误差小于1％。除B滤光片之外，在一定范围内圆顶平场和天空平场之间最大差异均小于1％。还给出了一些做好圆顶平场和天空平场的建议。
Using the sky flats and dome flats data of 1. 56m telescope, we analysed the differences between dome flats, sky foats, and the differences between sky flats and dome flats- The results indicates that dome flats are consistent as well as sky flats. Except the B filter, all the sky flats and dome flats show no significant differences (at the 1% level).' Suggestions are also given on how to get dome flat and sky flat better
