%description
CFITSIO is a library of C and FORTRAN subroutines for reading and writing data files
in FITS (Flexible Image Transmission System) data format. CFITSIO frees programmers
from the internal complexity of the FITS file format by providing a set of easy-to-use
high-level routines, thereby simplifying the task of writing software that processes
FITS files. At the same time, CFITSIO provides many advanced features, making it the
most widely used FITS file programming interface in the astronomy community.

%package -n fpack
Summary:             FITS image compression and decompression utilities
Requires:            %{name} = %{version}-%{release}

%description -n fpack
fpack can best compress images in FITS format, while funpack can
restore them to their original state.

* Lossless compression of images in integer format using the Rice compression algorithm.
* Compression ratio is usually 30% better than GZIP
* Compression speed is 3 times faster than GZIP
* Decompression speed is the same as GUNZIP

* Floating point images are compressed using a lossy algorithm
* Truncate image pixel noise by a user-specified amount to produce
a higher compression rate than lossless techniques
* The scientific measurement accuracy in the compressed image (relative
to the accuracy in the original image) depends on the amount of compression
