wcstools - access sky coordinates in astronomical images and search
astronomical catalogs
WCStools is a set of programs that helps
manipulating images (FITS files) and catalogs, in particular with their
World Coordinate Systems (WCS). NEMO has traditionally a poor WCS support,
and interfaces with WCStools may be useful. The table below lists a loose
functional comparision between the two packages where their functionality
is close.
