摘要
由理论计算和统计分析估计了佘山40厘米天体测量照相望远镜不同天顶距带内的光谱型差。研究了星等差与观测残差的关系。发现光谱型差和星等差对射电星的光学定位的影响不明显,在归算处理时可以忽略。
The spectral type errors in difference zones of zenith distances for the 40cm ast-rograph at Zo-Se are estimated from theoretical calculations and statistical analysis respectively, and the relation between magnitude differences and observational residuals are estimated as well. It shows from the above discussions that there are no significant effects of the spectral type error and the magnitude difference on optical determination of radio star positions, and they can be neglected in data reduction for the telescope.
