| 摘 要： | 美国国立光学天文台的IRAF软件系统,已成为国内光谱处理的主要计算机软件之一。由射电天文需要发展起来的FITS格式,已作为国际上交换磁带数据资料的通用格式。本文简单地介绍了FITS格式,讨论了如何将厚片CCD光谱观测资料转换为IRAF图像,继而转换为标准FITS格式。这对于使用IRAF系统进行光谱处理,以及国内国际间的资料交换是有用的。

| Abstract: | The IRAF system developed by NOAO has become one of the most principal software systems for spectra processing in China.The tape format "FITS",firstly developed to meet the needs for radio astronomy,has been one of the internationally general-service formats for tape data conversion.In this paper,based on the brief introduction of the FITS format,the problem of data conversion from the thick CCD spectral file to an IRAF image,in addition to the FITS format,is discussed.This is useful for the spectra processing by means of the IRAF software packages and for the data exchange at home and abroad. |
