Fig. 2
HCN integrated intensity for a density of 1016 cm-3, a kinetic temperature of 750 K and a HCN column density of 2 × 1015 cm-2 at a line width of Δv = 1 km s-1. For this density, the lines are close to the local thermal equilibrium (LTE). The same color scheme as in Fig. 1 is used. Only the strongest bands are labeled.
