Astronomical applications often deal with world or image pixel coordinates. This section describes some C++ classes that are used to represent coordinates. These are fairly simple classes that deal with abstract coordinates, such as (a, d, equinox ) for world coordinates or (x, y) for image coordinates. Another class, WCS , which is described in the next section, deals with coordinate conversion and FITS header keywords.
