Notes. Column 1: name of galaxy. The sources in bold hold clean maser disks (see Sect. 2). Column 2: 5 GHz peak flux density of the brightest component. Column 3: 5 GHz integrated flux. For detected sources with multiple components the reported flux is the sum of the fluxes from all the components. Column 4: J2000 right ascension and declination obtained (except for NGC 2273) from the second observations for the peak position of the brightest component. Column 5: right ascension and declination uncertainties. Column 6: spectral index obtained from 33 GHz VLA observation and 5 GHz VLBA observations assuming a power law dependence of S ∝ ν−α. Column 7: brightness temperatures. If the source is unresolved, a lower limit is given. Column 8: putative core of the AGN, corresponding to the component with highest brightness temperature. NW stands for northwestern, CN for central, and N for northern.
