Notes.

(a)

VLSR of two foreground components are from the p-H2O 111−000 line.

(b)

VLSR and FWHM of the envelope component is from HO lines.

(c)

VLSR and FWHM of the outflow component is from broad components seen the p-H2O 202−111, p-H2O 211−202, and o-H2O 312−303 lines.

(e)

A lower limit from HF 1–0 observations. Emprechtinger et al. (2012).

(g)

CO column density from C18O J = 9–8 observations assuming an abundance of 16O/18O of 540. San José-García et al. (2013).

(h)

The total (ortho+para) H2O column density assuming an o/p ratio of 3.

(i)

H2O column density for the envelope for a source size of 4″.

(j)

H2O column density for the outflow for a source size of 30″.
