RA-DEC from DSS headers

[Doug Mink]

The WCSTools package, at

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

has code to decode the DSS header information.  That code has
been included in the SAOimage, SAOtng, and Skycat image browsers
for several years now.  It is in C and is fairly modular for easy
inclusion in other software.  WCSTools includes programs to
convert lists of (x,y) coordinates to RA and Dec (J2000 or B1950)
and vice versa.
