Handle the WCS of a FITS image (development files)

 WCSTools is a set of software utilities, written in C, which create,
 display and manipulate the world coordinate system of a FITS or IRAF
 image, using specific keywords in the image header which relate pixel
 position within the image to position on the sky. Auxiliary programs
 search star catalogs and manipulate images.
