Notes.

(a)

Lines 1 and 2 correspond to the H2O (211 − 202) (νrest = 752.03 GHz, Eup = 137 K) and (202 − 111) (νrest = 987.93 GHz, Eup = 101 K) transitions, respectively.

(b)

νobs is the frequency corresponding to the zero of the velocity scale of the spectra of Fig. 1.

(c)

Sνpk corresponds to the peak continuum flux density (mJy/beam); Sν refers to the total spatially integrated continuum flux density (mJy).

(d)

SνH2Opk corresponds to the peak H2O flux density (mJy/beam); IH2Opk is the peak H2O velocity-integrated flux density (flux in one beam, in Jy km s-1/beam) and IH2O the spatially integrated H2O line flux (in Jy km s-1). The values derived for SDP.81 and G12.v2.30. are underestimated (see text).

(e)

μLH2O is the apparent luminosity of the observed H2O line using the relations given in, e.g., Solomon et al. (1992).

(f)

In the cases of SDP.9, G12.v2.30 and G15.v2.779, the H2O emission lines are double-peaked and the parameters in the table refer to double Gaussian fits.
