^a Distances have been estimated by using velocities taken from the NASA/IPAC Extragalactic Database (NED) and adopting a Hubble constant of $H_{\rm {0}}=\rm {75~ km ~s^{-1}~ Mpc^{-1}}$ .
^b Integrated flux densities, centre velocities, and full width to half maximum (FWHM) linewidths of the observed features are obtained from Gaussian fits.
^c Isotropic luminosities are derived from $L_{\rm {H_{2}O}}/[\hbox{$L_{\odot}$ }]=0.023 \times \int S ~ \rm {d}\textit{V}/[\rm {Jy \ km \ s^{-1}}] \times \textit{D}^{2}/[\rm {Mpc^{2}}]$ .
^d Values obtained by forcing the fit.
^e The water maser emission consists of two features.
^f The water maser emission consists of three features.
