X-ray to TeV γ-ray SED of LS 5039. The COMPTEL soft γ-ray spectra (sum of all data) for the INFC and SUPC orbital phases are combined with similar spectra from the X-ray (Suzaku, Takahashi et al. 2009), the MeV/GeV (Fermi/LAT, Hadasch et al. 2012), and the TeV band (HESS, Aharonian et al. 2006a) to build a high-energy SED of LS 5039. The SED shows that 1) the emission maximum at energies above 1 keV and 2) a switch in radiation dominance is occurring at MeV energies. The lines – solid and dashed – in the X-ray spectra represent the model calculations of Takahashi et al. (2009) on the emission pattern of LS 5039. They do not present a fit to their measured X-ray spectra.
