Comparison between the spherical-toroidal geometry and our RefleX simulations assuming the BNTorus geometry (Fig. 8) for two viewing angles and an half-opening angle of θ _OA = 30 deg. Top: i = 20 deg; bottom: i = 87 deg. In each panel, the top subplot shows the spherical-toroidal model (solid line) and the RefleX simulation (crosses); the bottom subplot shows the ratio between our simulations and the spherical-toroidal model. In all cases, the primary continuum is defined as a power law starting at 1 keV with an index Γ = 1.9 up to 500 keV. The equatorial column density is N_H,eq = 10²⁴ cm^-2. The BNTorus model has been approximated using 51 annuli in RefleX. Spectra are averaged over 2 deg in inclination. 10¹⁰ photons were generated.
