Notes. The spectrum type acronyms stand for: PL – power-law and PLC – cut-off power-law. Normalization factor N is given in units of 10−25 [ph/(cm2 s eV)]; normalization energy is set to E0 = 2 TeV for all the sources. The curvature parameter β = 0 in all cases. For the sources fitted with the power-law model the values of Ecut are not given. All uncertainties correspond to a 68% confidence interval.
