COMPTEL error location contours for the most significant COMPTEL detection of GRO J1823-12, obtained in the 10−30 MeV band for the sum of all data. The contour lines are plotted on a map in galactic coordinates (l,b) of the LS 5039-region. The error contours start with 1σ in steps of 1σ. The sky positions (circles) of all γ-ray sources, listed in the second Fermi catalog and are within a search radius of 2° around the pixel center of the best-fit source location (l/b:17.5°/−0.5°) are shown.
