Fig. 6.
Left: best-fit spectra for the BLR ring geometry to the combined Fermi-LAT and H.E.S.S. data. Both data sets are corrected for EBL absorption following Franceschini et al. (2008). The spectral shapes do not change significantly, if the shell geometry is assumed instead. Right: likelihood profile as a function of the distance r for the different assumed intrinsic spectra and BLR geometries.
