P1 (top) and P2 (bottom) SED. The differential upper limits are represented by the black arrows. The blue dashed line represents the SED computed using five years of Fermi-LAT data assuming a SEC function, between 100 MeV and 100 GeV, and the dot-dashed line the fit of SED to an EC function. The dot-dot-dashed line is the result of the fit of the Fermi data above 10 GeV with a power law. The statistical error contour from the power-law fit is also plotted.
