In this paper I investigate the γ-ray spectra of AGN by summing up the
intensity and the power-law fit statistic of Quasars and OVV's and BL Lac's
separately. The spectrum of the average AGN is softer than that of the
extragalactic γ-ray background. It may be that BL Lac's, of which the
average has a harder spectrum than Quasars, make up the bulk of the
extragalactic background. We also find cut-offs both at low and at high
energies in the spectra of Quasars and OVV's, however only at the time of
γ-ray outbursts. While the cut-off at high energies may have something
to do with opacity, the cut-off at low energies may be taken as indication that
the γ-ray emission of Quasars is not a one component spectrum.Comment: 4 pages, Proceedings of Heidelberg workshop on gamma-ray emitting AG
