Description


This survey is a maximum entropy solution to the data taken by the CompTel instrument on the <i> Compton </i> Gamma Ray Observatory. The data in this survey are intended only to give the general appearance of the MeV gamma-ray sky. Fluxes, flux limits and spectra should be derived using the Compass system for the analysis of CompTel data. Compass is available at the <a href="https://web.archive.org/web/20100622161007/http://wwwgro.unh.edu/comptel/compass/compass_users.html"> Compton Observatory Science Support Center </a>. <P> The maps were originally generated by the CompTel Instrument Team as three separate maps in the bands: <UL> <LI>1-3 MeV <LI>3-10 MeV <LI>10-30 MeV </ul> <P> All CompTel observations from phases 1, 2 and 3 were included in the maps (May 1991 through October 1994). These maps were combined into a single 3-D map at <i> SkyView </i> <P> Provenance: CompTel Instrument Team. Maps generated by Andrew Strong, Max-Planck Institute for Extraterrestrial Physics (Garching).. This is a service of NASA HEASARC.
