H.E.S.S. exposure-corrected excess counts image of HESS J1808−204 towards the stellar cluster Cl* 1806−20 (red cross), containing SGR 1806−20 and LBV 1806−20. The image is Gaussian smoothed with standard deviation 0.06° corresponding to the 68% containment radius of the H.E.S.S. analysis PSF, which is also indicated by the white circle at the bottom left corner. Pre-trial excess significance contours (6, 5, 4σ levels) for an integration radius of 0.1° are indicated by black solid lines. The dark green solid point with error bars (1σ statistical) and white dashed ellipse represent the fitted location and radius of the intrinsic Gaussian source model. The 68% location error of 3FGL J1809.2−2016c (Fermi-LAT GeV source) is indicated by the magenta dashed ellipse.
