Radial profiles of selected quantities: gas density ρ [cm⁻³], average temperature T_avg [K], and average Compton y_avg (Eq. (46)), measured at different depths in the disk atmosphere. Values at τ = 0.1, τ = 1, and τ = 10 are shown by dashed blue lines, at temperature minimum (τ_cor) by the green line, at thermalization depth by the red line, and at the corona base (determined by temperature minimum or thermal instability in case it is developed) with the black dotted line.
