Fifth SKIRT benchmark (Sect. 4.2.2), comparing SKIRT simulations of a torus model against the corresponding RXTORUS model spectra as calculated with REFLEX. The opening angle of the ring torus is 60°. The equatorial hydrogen column density N_H of the torus is indicated on the figure, for each simulation. Left: scattered photon flux, for a line of sight not intersecting the obscuring torus (i = 45°). Right: scattered photon flux, looking through the obscuring torus (i = 75°). We find an excellent agreement between both codes, for all column densities and sightlines.
