Application of Spectral Analysis Softwares in Astronomy

With the planning,implementation and operation of large-scale spectroscopic survey projects,automatic analyses,efficiently collections and quickly extracting effective physical information from the huge volume of astronomical spectral data is the focus of astronomers and an important issue of contemporary astronomical researches.Most of astronomy researches are based on the spectral analysis.Various rapidly developed spectral analysis tools are of promoting significance to easily explore the spectral characteristics in view of their convenience and usability.In this paper,the relevant background of the several completed,running and upcoming spectroscopic survey projects are described,and the importance of applying spectral tools is pointed out.Taking VOSpec,VOSED,SpecView,Iris,SPLAT,CASSIS,ASERA for example,the basic features and main functions of theos spectral analysis tools are introduced,and then the applications and operating environments of these tools are compared,The research in this paper provides the certain reference and guidance for astronomers to select the analysis software.
