The table provides the spectral channel number (Col.~1), the velocity (in respect to 
the local standard of rest) of the detected water maser components (Col.~2), the absolute 
coordinates (RA and Dec at~J2000) 
of each feature (Cols.~3 and~4, respectively), flux of 
each maser component and the corresponding flux
error (Cols.~5 and~6, respectively), and 
the position uncertainty of each component (Col.~7).
