Notes.
The H2O and CO abundances of each gas component are obtained from the H2O and CO column densities after correcting for the relative beam filling factor.
See the B2-2 model from Santangelo et al. (2012), shown in their Table 2. The H2O column density is, however, slightly different because it has been derived using the collisional rate coefficients from Dubernet et al. (2006, 2009) and Daniel et al. (2010, 2011).
