Notes. In this analysis, the following lines are used: H2O lines at 179.5 μm, 125.4 μm, 108.1 μm, and 90.0 μm; CO lines at 162.8 μm, 124.2 μm, 108.7 μm, and 90.2 μm; OH lines at 79 μm and 84 μm. Median values of the fractions calculated from 18 sources with line detections are adopted in case of observations (column Obs.).
