Spectra of NGC 1275, Cen A core, NGC 6251, PKS 0625-35, 3C 380, SBS 0846+513, 1H 0323+342, and PMN J0948+0022 measured in the energy range from 100 MeV to 300 GeV, which showed deviation from the simple PL model above several GeV (see the text). The best fit models obtained with gtlike are depicted together with spectral points, which have been obtained by separately running gtlike for smaller energy intervals. The corresponding parameters are given in Table 2.
