Software utilities to display and manipulate the WCS of a FITS image

http://tdc-www.harvard.edu/wcstools

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.
