Seventh SKIRT benchmark (Sect. 4.2.4), comparing SKIRT simulations of a torus model against the corresponding XARS spectra. The opening angle of the wedge torus is 60°. The equatorial hydrogen column density N_H of the torus is indicated on the figure, for each simulation. Left: total photon flux, for a line of sight not intersecting the obscuring torus (i = 45°). Right: total photon flux, looking through the obscuring torus (i = 75°). Both codes are in excellent agreement. The small offset below 12.5 keV is explained by differences in the atomic data (see text).
