Notes. The luminosity ratios between each H2O line and their total infrared, and the velocity-integrated flux density ratio of different H2O transitions. Td is the cold-dust temperature taken from B13, except for the ones in brackets which are not listed B13, that we infer them from single modified black-body dust SED fitting using the submm/mm photometry data listed in Table 2. All the errors quoted for Td are significantly underestimated especially because they do not include possible effects of differential lensing and make the assumption of a single-temperature. Line ratios in brackets are derived based on the average velocity-integrated flux density ratios between 211–202and 202–111lines in local infrared galaxies. The local strong-AGN sources are the optically classified AGN-dominated galaxies and the local H ii+mild-AGN sources are star-forming-dominated galaxies with possible mild AGN contribution (Y13). The first group of the sources are from this work; and the sources in the second group are the previously published sources in O13; the third group contains the previously published high-redshift detections from other works: HFLS3 (Riechers et al. 2013), APM 08279 (van der Werf et al. 2011), HLSJ 0918 (Combes et al. 2012; Rawle et al. 2014) and SPT 0538 (Bothwell et al. 2013); the last group shows the local averaged values from Y13.
