Results of the additional Monte Carlo simulation for i = 50° and the partially transparent cone with Θ = 40° and ρ = ρ_c, illuminated by a central unpolarized isotropic primary power-law radiation with Γ = 2. We show the observed total spectra (top), EF_E, corrected for the slope of primary radiation; the corresponding total polarization degree (middle), p; and the average number of scattering events before detection (bottom), N_scat, versus energy. In the color code, we show from red to blue different cases of equatorial column density: N_H = 10²², 10^22.5, 10²³, 10^23.5, 10²⁴, 10^24.5, 10²⁵, 10^25.5 cm⁻², respectively. The solid lines represent a fully neutral obscurer, the dashed lines represent a fully ionized obscurer. In dotted lines we show examples of the energy-independent analytical polarization prediction from Brown & McLean (1977) valid for low N_H and full ionization. In dot-and-dash black lines, we show the intrinsic emission. In light gray in the background, we overplot all polarization curves from the middle left panel in Fig. 3. All spectra are renormalized to intrinsic luminosity L_X = 10³⁷ erg/s and distance D = 3 kpc.
