Test statistics map for photon energies 10 ≤ E ≤ 300 GeV. The cyan circle denotes the error circle of the best fit position of the LAT source in this energy band and the black circle indicates the intrinsic width of the H.E.S.S. source. Overlaid in green are CO contours (Dame et al. 2001) of the foreground molecular cloud located at a distance of ≈ 400 pc (− 10 to 0 km s^-1) and measured in units of average temperature (from 0.75 to 1.5 K in steps of 0.25 K).
