Notes. We report a 1σ abundance range (rather than an upper limit) when (i) the posterior shows a peak, and not a flat uniform distribution and (ii) the lower 1σ abundance limit is superior to −9. Besides H2O and CO, the HDO distribution has the highest peak and is the only one with a 2σ lower bound > −9 regardless of the temperature model.
