Model 5. Upper panels: (left) gas temperature, (right) dust temperature. Central panels: (left) hydrogen number density, (right) optical depth of the line (τ_line), of the continuum (τ_cont), cumulative vertical flux, and number density as a function of the radius for the [O i] line at 145 μm. The box in thick black lines represents the region in the disk that emits 70% of the line radially and 70% of the line vertically, thus approximately ~50% of the line flux. Lower panels: similar plots for the [C ii] line at 157 μm (left) and the ortho H₂ 0−0 S(1) at 17 μm (right).
