Notes. The models are: PexTH: tbabs(zpcfabs*pexmon+mekal); PexiTH: tbabs(zpcfabs*absori*pexmon+mekal). The photon index of the power law has not been allowed to vary below 1.1. All fluxes and luminosities are unabsorbed. The flux of the AGN component has been corrected by a factor of 5, considering that the central (excluded) region contains 80% of the PSF. The errors on AGN fluxes are the average errors of the reflected and direct component.
