Notes. Uncertainties are indicated in parentheses.

(a)

Corrected fluxes obtained for a common angular resolution of .

(b)

LVG predicted fluxes for the best-fit model of the warm component (Tkin = 250 K, n(H2) = 106 cm-3, N(o-H2O) = 2 × 1014 cm-2, N(p-H2O) = 7.0 × 1013 cm-2, and a source size of 10′′) and using an OPR H2 of 0.5 (see Sects. 4.2.1. and 4.2.2).

(c)

LVG predicted fluxes for the best-fit model of the hot component (Tkin = 1000 K, n(H2) = 2 × 104 cm-3, N(o-H2O) = 7 × 1016 cm-2, N(p-H2O) = 2.1 × 1016 cm-2, and a source size of ) and using an OPR H2 of 3 (see Sects. 4.2.1. and 4.2.2).

(d)

Flux after removing the contribution of the extended component detected in the 556.9 GHz line (see Sect. 3.3).
