Notes. Column 1: name of galaxy. The sources in bold hold clean maser disks (see Sect. 2). Column 2: J2000 right ascension and declination. For NGC 5765b, NGC 6323, NGC 6264, and UGC 9639 the coordinates are taken from NED, and for the remaining sources the coordinates are from Kamali et al. (2017). Column 3: fringe finders. Column 4: phase calibrators. Column 5: right ascension and declination uncertainties. The second VLBA observations are presented in the lower part. The pointing coordinates for the second observations were taken from the first run of VLBA observations.
