Significance map computed from the H.E.S.S data with an correlation radius of 0.06°. The estimated position and density of molecular clouds in the region are indicated by the dashed lines. Additionally, the morphology of the best-fit model derived in the analysis of the Fermi-LAT and H.E.S.S. data is indicated. Only clouds with a distance between 4 kpc and 12 kpc and a large positional overlap with the extended emission observed in Fermi-LAT and H.E.S.S. are depicted in the counts map.
