Notes. When the symbol for a molecular species is underlined, its fractional abundance is above 1 $\times $ 10-10 otherwise it is simply above 1 $\times $ 10-12 (limit of detectability assumed). The temperature mentioned in the Col. 6 is self-consistently determined at the particular value of $A_{\rm v}$ shown.
