Left: Fermi-LAT (open circles) and H.E.S.S (dots) combined spectrum fit with a power law. Right: Fermi-LAT and H.E.S.S combined spectrum fit with a power law with an exponential cutoff (blue) and a broken power law (green). For both figures, the best-fit functions are shown with 68% error bars inthe shaded region, as well as residuals compared to the fit. The flux point error bars represent the statistical uncertainties. The fit parameters are reported in Table 1.
