摘要
以俄罗斯SAO 6米望远镜的多目标光纤光谱 (multi object fiber spectra)为例 ,介绍了多目标光纤光谱的观测方法和数据处理的一般过程 .分析了影响精度的主要误差来源 .根据所用软件和仪器的情况 ,对散射光、相对透过率、波长定标、流量定标等问题作了相应的讨论和适当改进 .
With the data obtained by the multi object fiber spectrometer of SAO 6 meter telescope, the general processes of the observation and data reduction of the MOFS are interpreted. The main error sources are analyzed. To perform better sky subtraction, some steps such as the scatter light, relative fiber transmission, wavelength and flux calibrations are modified and discussed according to the conditions of instruments and software.
