| 摘 要： | 介绍了云台太阳光谱望远镜光栅鬼线强度测量方法。给出了２ 级光谱罗兰鬼线强度的初步测量结果， 为母线强度的０ ．０４９ ％ 。结果表明光栅的质量优良， 鬼线对光谱测量的影响非常小， 一般情况下在光谱资料处理中可以不必考虑鬼线强度的改正

| Abstract: | A method of measuring the intensity of the Ghost line produced by the grating is given for the Solar Spectral Telescope at Yunnan Observatory in this paper.A preliminary result about the intensity of the Rowland Ghost line for the second order spectrum is obtained.The intensity of the Ghost line is 0.049% of the main line. It is indicated that the Ghost line is very weak compared with the main line and the grating is excellent in quality.An influence of the Ghost line to spectral measurement is very small,in general,it is not necessary to correct the influence in spectral data processing. |
