| 摘 要： | 简单介绍了用于读写FITS格式文件的FITSIO软件包的主要功能和特点。利用该软件包对 SDSS(Sloan Digital Sky Survey)数据中椭圆星系NGC4044和漩涡星系NGC5227的g,r,i三个波段的 FITS图像文件进行了重新读写,使这三个波段的FITS文件中天体的坐标完全对应。并以此合成了“真彩图”和“颜色分布图”,可以清楚地看出这些星系不同位置处颜色的变化。

| Abstract: | FITSIO package, mainly used to deal with FITS data, is introduced in this paper. By using subroutines in FITSIO, SDSS images of NGC4044 and NGC5227 in g, r, i bands are rebuilt after matching their pixels in a common celestial coordinate system. Then, RGB images of these 2 galaxies , as well as their color distributions are plotted, which clearly showed the color variation of stellar components depending on their locations. |
