COMPTEL observations of active galactic nucleiThe number of AGNs (Active Galactic Nuclei) that might be observed by COMPTEL (Compton Telescope) around 1 MeV is of the order of two dozens or less. The estimate is based on the HEAO-1 (High Energy Astronomy Observer) measurements between 2 keV and 100 keV and on the assumption that the power law spectra of AGNs at x ray energies extend to at most 3 MeV before they break off.
