Program Purpose

The MAPGEN program generates maps of gamma ray events in FITS format files to be plotted by any FITS reader such as the SKYMAP program. The gamma ray data is extracted from the Summary Data Base (SMDB) or the SELECT data base according to user specified time range, energy level, coordinates, energy return codes and so on. The data is then binned according to the events arrival directions in a user selected coordinate system and grid style. Finally, the program stores the binned data in FITS format files using the energy levels as a third dimension of the maps.
