Orbital light curve of LS 5039 in the 1030 MeV COMPTEL band for the sum of all data. The light curve is folded with the orbital period of ~3.9 days and given in phase bins of 0.2. The two broader phase periods, defined as INFC and SUPC, are indicated. A flux increase during the INFC period is obvious. In the phase bin containing the inferior conjunction, the source is roughly three times brighter than in the phase bin containing the superior conjunction. In general the 1030 MeV γ-ray light curve is consistent in phase and amplitude with the one at TeV γ-rays.
