Measured photon index versus intrinsic absorption for the Seyfert galaxy sample. The lines correspond to the measured photon index obtained from a simple power law fit of simulated power law spectra with intrinsic photon index Γ = 1.6, 1.9, and 2.2 (from bottom to top) modified by the corresponding NH. Upper limits on NH are indicated with arrows.
