提出和完善了一个分析类星体能谱数据的方法.利用该方法,可以发现并测出类星体的吸收线.文章还通过取自Sloan Digital Sky Survey样本的3个类星体的能谱数据,演示了采用该方法证认MgII吸收线的结果
We develop a method of analyzing the spectral data from quasar surveys.With this method,one can detect and measure absorption lines of quasars.The method is described in detail in this paper.In addition,we illustrate the method by identifying MgII absorption lines from the data of three quasars taken from the Sloan Digital Sky Survey.
