Two dimensional structure of the reference disk model CI_XN. The height of the disk z is scaled by the radius (z/r). From top left to the bottom right: a) gas number density n_{⟨ H ⟩}; b) dust density ρ_dust (note the dust settling); c) FUV radiation field χ in units of the ISM Draine field; d) gas temperature T_gas; e) dust temperature T_dust and f) the vertical hydrogen column density N_{⟨ H ⟩ ,ver} versus radius. The white dashed contour lines in each contour plot correspond to the levels shown in the respective colorbar. The black (red) solid contour in panel c) indicate a vertical (radial) visual extinction equal to unity.
