Fig. 5
Schematics of the abundance models for the transitions of DCO+J = 3 − 2, DCN J = 3 − 2 and N2D+J = 3 − 2. The dashed blue line corresponds to a scaled profile of the column density of the abundance model for the purpose of illustration. The red continuous line corresponds to the assumed excitation temperature profile.
