AGN X-ray spectra from the TORUS model of Brightman & Nandra (2011). The intrinsic power law has a photon index of Γ = 1.9. Labeled numbers indicate the obscurer column density NH = 1022−25 cm−2 . At high column densities, the Fe Kα line at 6.4 keV becomes prominent. A unobscured power law component normalized to 1% of the intrinsic power law has been added.
