Table 1: Target galaxies: Source name, coordinates, redshift, 178 MHz total flux, 5 GHz core flux, [O III] line Equivalent Width, maser luminosity and observed velocity range are given. The data were taken from the NASA/IPAC extragalactic database (NED), from Table 1 of Chiaberge et al. (2002) and references therein, and from the observations presented here.
