COMPTEL 1−3 (left), 3−10 (middle) and 10−30 MeV (right) maps, generated in galactic coordinates (l,b), show the statistical evidence of GRO J1823-12 for the sum of all data. The contour lines start at a detection significance of 3σ (1 d.o.f. for a known source) with a step of 0.5σ. The location of the microquasar LS 5039 (diamond, l/b: 16.88°/−1.29°) and the lensed quasar PKS 1830-210 (square) are indicated; i.e., the locations of the simultaneously fitted COMPTEL sources. The quasar PKS 1622-297 and a possible source at the Galactic center, both out of the plot region, were also taken into account in the simultaneous fitting. The 10−30 MeV band yields the highest detection significance (7.8σ) at the position of LS 5039.
