Top panel: extract in the 5.5–7.5 keV region of a spectrum simulated using the model of Ikeda et al. (2009). The model has a torus with a half-opening angle of θ_OA = 46.2° (equivalent to log L_X = 42.7, according to the relationship of Hasinger 2008), an equatorial column density of , and an inclination angle of θ _i = 1°. The continuous line represents the fit to the simulated spectrum using for the continuum the same model we used for the simulations and a Gaussian line for the iron Kα fluorescent line. Bottom panel: contribution to the chi-squared for the best fit to the simulated spectrum.
