Notes. Observed H2O line properties of G09v1.97-R. We adopt μR−line = 20 for the magnification of the velocity-integrated line fluxes of G09v1.97-R (Y19).

(a)

Here, we include an additional 15% uncertainty considering the possible contamination from the interacting region (Y19).

(b)

The value is taken from the NOEMA detection by Yang et al. (2016) of the redshifted component for consistency in the comparison with the other lines detected here, which are also dominated by the redshifted component (G09v1.97-R).

(c)

Here, we adopt a fixed line width for G09v1.97-R of 250 km s−1, according to Yang et al. (2016).
