标题： Reduction of CCD observations with scanning Fabry-Perot interferometer

摘要： 描述了用于6米望远镜SCORPIO新型焦平面还原器的Fabry-Perot干涉仪模式下获得的数据的算法。重点介绍了通道光度校正和夜间天空发射减除的程序，这对于与光电倍增管相比使用CCD进行观测尤为重要。研究了各种误差源对数据立方体径向速度测量的影响。给出了利用星系NGC 6951的发射线和球状星团M 71的吸收线构建速度场的例子。 显示英文摘要

摘要： The algorithms used for reduction of data obtained in a Fabry-Perot interferometer mode of the new focal reducer of the 6m telescope SCORPIO are described. The main attention is focused on the procedures of photometry correction of channels and night sky emission subtraction, which is especially important for observations with a CCD in comparison with a photon counter. The influence of various sources of errors on measurements of radial velocities in a data cube is investigated. Examples of velocity field construction by using emission lines in the galaxy NGC 6951 and absorption lines in the globular cluster M 71 are presented.
