摘要
根据陕西天文台中星仪恒星光电测光资料,讨论星等计算中的色改正问题。通过探测器光谱响应特性的分析及实测资料,给出一组星观测的色改正值。考虑色改正后的星等计算值与GC星表星等相比较,得出一组星的星等测定值与星表值之误差的平均为±0.06~m。
Using the data of the stellar photoelectric observation with the Transit In-strument at Shaanxi Astronomical Observatory, the colour correction for the stellarmagnitude determination was discussed. Based on the analysis for the spectral res-ponse of the detector and the practical observed data, values of the colour correc-tion for a group of observed stars was given. The Colour correction was consideredfor the calculation of magnitudes. Comparing the computed magnitudes with magni-tudes taken from GC Catalogue, their average difference over one group of starswas±0~m.06
