Notes. Observed CO line flux is taken from Banzatti et al. (2017), and H2 and H2O fluxes are extracted from the Spitzer-IRS spectra using the method in Banzatti et al. (2012). The table denotes the upper level energy of the dominant transitions of each blend according to our model. The H2 S(2) line is contaminated by an OH line; the contribution of the OH line was estimated by taking the average flux of two adjacent OH lines.
