Fermi/LAT countmaps of the region around Porphyrion in the energy ranges 50 MeV < Eγ < 100 MeV (top) and 100 MeV < Eγ < 1000 MeV (bottom). The size of the Porphyrion source is smaller than the size of the cross at the source position. The brighter spots in the lower image are sources other than Porphyrion detected by Fermi/LAT.
