Table 3:

Overview of best fitting spherical envelope models.
Isotopologue Outer abundancea Comment

o-H218O  		$3\pm 1 \times 10^{-10}$ implies o-H2O  $1.7~\pm~0.5\times10^{-7}$b
p-H218O  $\le 3 \times 10^{-11}$ implies p-H2O  $1.7\times10^{-8}$b
o-H2O  $3\times 10^{-7}$ Well constrained by both excited para lines
p-H2O  $3 \times 10^{-8}$ $\ge$10-8 required for self-absorption

Notes. (a) The relative abundance of species listed, and not total H2O
(b) Assuming 16O/18O = 550.
