module for handling World Coordinate Systems (WCS)
(c) 2007-2009 Matt Hilton
This is a higher level interface to some of the routines in PyWCSTools (distributed with astLib). PyWCSTools is a simple SWIG wrapping of WCSTools by Doug Mink (http://tdc-www.harvard.edu/software/wcstools/). It is intended is to make this interface complete enough such that direct use of PyWCSTools is unnecessary.

Finds the minimum, maximum R.A. and dec. coords that overlap between wcs1 and wcs2. Returns these coordinates, plus the corresponding pixel coordinates for each wcs. Useful for clipping overlapping region between two images.
