英文摘要This paper presents a comprehensive analysis of the photometric system of the University of Chinese Academy of Sciences 70 cm Telescope located at the Yan-qi Lake campus of the University of Chinese Academy of Sciences. We evaluated the linearity, bias stability, and dark current of the camera. Utilizing the Johnson-Cousins BlueVisible-Red-Infrared filter system and an Andor DZ936 charge-coupled device camera, we conducted extensive observations of Landolt standard stars to determine the color terms, atmospheric extinction coefficients, photometric zero-points, and the sky background brightness. The results indicate that this telescope demonstrates excellent performance in photometric calibration and good system performance overall, meeting the requirements for limited scientific research and teaching purposes.
