Same as in Figure A.1., but for the best χ² solutions obtained using simulations that include mechanical heating as discussed in Section 4.5. Top: Fe II spectrum assuming equal contribution from bright and dark sides, displayed with a 4% covering factor. The Fe II template corresponds to the CLOUDY simulation associated with logΦ(H) = 18 cm⁻² s⁻¹, log(P_tot) = 14.75 cm⁻³ K, Z=Z_⊙ and V_turb = 100 km s⁻¹. Bottom: Fe II spectrum assuming a 20% contribution from bright sides and 80% from dark sides, displayed with an 8% covering factor. The Fe II template corresponds to the CLOUDY simulation associated with logΦ(H) = 18.25 cm⁻² s⁻¹, log(P_tot) = 14.75 cm⁻³ K, Z=Z_⊙ and V_turb = 100 km s⁻¹.
