Overview of the DALI model output. The four panels left top (A−D) present the gas and dust density structure and the gas and dust temperature, respectively. The other panels present the molecular abundances of the molecular transitions in the most representative DALI model, assuming a gas-to-dust ratio of 25 and a carbon depletion factor of 4. The white contours represent the region where 95% of the emission originates, the black lines show the τ = 1 surface for the optically thick emission lines.
