Notes. The columns show the clump name, the number of Gaussian components in the spectrum, the range of VLSR over which we detect emission, the flux density peak, the integrated emission, the water maser luminosity, the VLSR and ΔV of the strongest component (S.C.), and the offset of the maser spot with respect to the phase centre (Ph.C.). No correction was performed for the primary beam.

(a)

These sources have poor uv-coverage, thus no position for the maser spots is given.
