Abstract

This paper studies the photometric accuracies of the YNAO 1.2 m telescope. The equations to transform observed magnitudes to the standard system are established by observing a set of Landolt standard stars. The relations between transformed magnitudes and standard magnitudes are also discussed. Our results show that the photometric system of the 1.2 m telescope is very close to the standard Johnson system. The paper finally lists the photometric precisions. The results indicate that the measurement precision of the V band is 0.041 mag for objects brighter than 13.5 mag under photometric conditions.
