Fpack和Funpack用户指南：FITS图像压缩实用程序
Fpack and Funpack User's Guide: FITS Image Compression Utilities
摘要：
Fpack是一个实用程序，用于最佳压缩FITS（灵活图像传输系统）数据格式的图像（参见http://fits.gsfc.nasa.gov）。相关的funpack程序将压缩的图像文件恢复到其原始状态（如果使用无损压缩算法）。(An压缩FITS二进制表的实验方法也可用;见第7节）。这些程序可以从主机操作系统命令行运行，类似于gzip和gunzip实用程序，只是它们针对FITS格式图像进行了优化，并提供了更广泛的压缩选项。
英文摘要：
Fpack is a utility program for optimally compressing images in the FITS (Flexible Image Transport System) data format (see http://fits.gsfc.nasa.gov). The associated funpack program restores the compressed image file back to its original state (if a lossless compression algorithm is used). (An experimental method for compressing FITS binary tables is also available; see section 7). These programs may be run from the host operating system command line and are analogous to the gzip and gunzip utility programs except that they are optimized for FITS format images and offer a wider choice of compression options.
