Notes. Column 2 gives source Galactic coordinates; Cols. 3 and 4 are equatorial coordinates. We give the absolute position of the maser component with maximum intensity. For the other components, we list position offsets relative to the position of the strongest component. The position uncertainties are ± 0.″18 and ± 0.″13, in RA and Dec, respectively (see Sect. 3). For each feature, Col. 5 gives the LSR radial velocity of the peak. Columns 6 and 7 are the peak and integrated fluxes at the channel corresponding to the peak of the feature. Column 8 gives the common source names used in the literature.
