Fig. 5
Variation of the maximum depth of the spectral features as a function of column density at excitation temperatures of 200 K (red), 500 K (blue) and 1000 K (black). The 3σ observational limit for IRS 46 is marked with a black dotted line and the colored dashed lines show the corresponding upper limits on the column densities for the three temperatures.
