Sixth SKIRT benchmark (Sect. 4.2.3), comparing SKIRT simulations of a torus model against the corresponding BORUS02 model spectra as calculated with BORUS. 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: scattered photon flux, for a line of sight not intersecting the obscuring torus (cos i = 0.75). Right: scattered photon flux, looking through the obscuring torus (cos i = 0.25). Above 30 keV, we find a significant mismatch between both codes for all sightlines. For unobscured sightlines (cos i = 0.75), the simulation results also diverge for energies below 10 keV.
