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.
