Results of our edge-on models described in Sect. 3.4. The panels show the gas temperature T (upper panels), IFIR, I[ C ii ], I[ C ii ]/IFIR, and ICO (1 − 0) (middle panels) and C+, C, and CO fractional abundances (lower panels) versus physical scale, for the gas densities nH = 3.0 × 103 cm-3,1.6 × 104 cm-3,4.0 × 104 cm-3 (left to right panels), and AV,los = 0.5, 2.5, and5.0. We note that the gas temperature does not vary with AV,los.
