Abstract

We have done photometric calibration of the 60 cm Nedeljkovic telescope equipped with the FLI PL 230 CCD camera, mounted at the Astronomical Station Vidojevica (Serbia), using standard stars from the Landolt catalog. We have imaged 31 fields of standard stars using Johnson's BVRI filters during three nights in August 2019. We have measured both extinction and color correction. Relating our calibrated magnitudes to the magnitudes of standard stars from the Landolt catalog, we have achieved accuracy of 2%-5% for the BVRI magnitudes.

Nedeljkovic望远镜的BVRI光度校准

我们使用Landolt目录中的标准恒星，对安装在Vidojevica（塞尔维亚）天文台的60厘米Nedeljkovic望远镜进行了光度校准，该望远镜配备了FLI PL 230 CCD相机。在2019年8月的三个晚上，我们使用Johnson的BVRI滤波器对31个标准恒星场进行了成像。我们测量了消光和颜色校正。将我们校准的星等与Landolt星表中标准恒星的星等相关联，我们获得了2%-5%的BVRI星等精度。
