+A package for reading and writing FITS files and manipulating their

+A module for reading and writing Flexible Image Transport System
+(FITS) files.  This file format was endorsed by the International
+Astronomical Union in 1999 and mandated by NASA as the standard format
+for storing high energy astrophysics data.  For details of the FITS
+standard, see the NASA/Science Office of Standards and Technology
+publication, NOST 100-2.0.
