Test statistic maps of LS 5039 for inferior conjunction (left) and superior conjunction (right) phase intervals derived by jointly fitting the four standard COMPTEL energy bands, covering 0.75–30 MeV. The location of LS 5039 is shown by a white plus symbol, and contours show the 1σ, 2σ% and 3σ location uncertainties. The quasar PKS 1830-210 was included in the source model and hence is not visible in the maps.
