^a These results are for the one-flavour CO desorption model.
^b The fraction of the disk mass with respect to the total accreted mass ( $M=M_\ast+M_{\rm d}$ ).
^c The fractions of warm ( $T_{\rm d}>18$ K) and hot ( $T_{\rm d}>100$ K) material with respect to the entire disk. The warm fraction also includes material above 100 K.
^d The fractions of gaseous CO and H₂O with respect to the total amounts of CO and H₂O in the disk.
