㈠ Scisoft是什么

Scisoft 是一个天文软件集，也是欧洲南方天文台(ESO)的一个项目计划，里面的大部分软件都是ESO以为的开发，都由ESO集合到这个套件里。集成了IRAF、 MIDAS、IDL、Gildas等数据处理软件，SAOImage、DS9、XPA、Skycat、fv等图像显示工具，SM、PGPLOT、 Grace、ggobi等绘图工具，python、MultiDrizzle、PyRAF等编程环境，GSL、DISLIN、LAPACK、FFTW、 CFITSIO等科学程序库，以及wcstools、Terapix Software Tools、Xephem、dss&dss2等常用工具。
但是这个软件集没有WINDOWS版本的，只有Linux、Solaris、HP-UX、Mac OS X，大部分天文台都是用的自己开发的系统进行处理，目前比较多的就是LINUX。
下面是整个Scisoft软件套件的内容：
