$^{{\rm a}}$ Using the optically thin LTE approximation with H218O and T=72 K and 25 K for KL and 2$^\prime $S, respectively.
$^{{\rm b}}$ Assuming an H218O Gaussian source size of 15 $^{\prime\prime}$.
$^{{\rm c}}$ For $N(\mbox{H$_{2}$ })=3\times10^{21}$ cm-2 (shocked outflow component).
$^{{\rm d}}$ For $N(\mbox{H$_{2}$ })=5\times10^{22}$ cm-2 (total H2 column through outflow).
$^{{\rm e}}$ For $N(\mbox{H$_{2}$ })=10^{22}$ cm-2.
