22 GHz water maser spot maps and spectra of components (a) I-2, (b) I-3, and (c) I-4 from epoch I. The plots are colour-coded by radial velocity (see the colour bars for the colour scale). The markers on the spectra correspond to the maser spots on the map. The diameter of each spot is proportional to the flux. The positional offsets are relative to the (a) MM2, (b) MM4, and (c) MM5 (star markers) positions from Brogan et al. (2019).
