Results of the fit of a pair-production-absorbed power-law to the HE and VHE spectra of 1FGL J1018.6–5856, with solid (dashed) lines indicating the absorbed (intrinsic) spectra. The emitter is assumed to be in the plane of the sky with respect to the star (i.e., on the plane of an orbit with ). The model with the maximum absorption compatible with the VHE spectral data is shown in red, the best-fit model with in green, and the best-fit model with no absorption in blue. Observational points are the same as in Fig. 1.
