摘　　要：北京师范大学参与共建的85 cm光学望远镜是中国科学院国家天文台兴隆观测站的主力观测设备之一.利用该望远镜在2019年5月12日的非常规观测数据,构建了其在B、V、 R、 I 4个波段的夜天光平场,并与相应的天光平场进行了比较.发现天光平场改正的典型误差在0.5%左右,全视场最大可达1.5%–2.0%.同时,还构建了I波段夜天光背景的Fringing模型,并开放给该望远镜用户使用.The 85 cm telescope is a well-operated prime focus system with high science outputs at the Xing-long station.Using unconventional data obtained on May 12,2019,super-sky flats in B,V,R,and I bands are constructed and compared to their corresponding sky flats.It is found that typical flat-fielding errors using sky flats are 0.5%for the four bands,but the maximum errors can reach 1.5%–2.0%.Fringing pattern with super-sky flat is also constructed for I band data and publicly available to the community.
