How To Install fpack on CentOS 8
Introduction
In this tutorial we learn how to install fpack on CentOS 8.
What is fpack
fpack optimally compresses FITS format images and funpack restores them to the original state. * Integer format images are losslessly compressed using the Rice compression algorithm. * typically 30% better compression than GZIP * about 3 times faster compression speed than GZIP * about the same uncompression speed as GUNZIP * Floating-point format images are compressed with a lossy algorithm * truncates the image pixel noise by a user-specified amount to produce much higher compression than by lossless techniques * the precision of scientific measurements in the compressed image (relative to those in the original image) depends on the selected amount of compression
