The interesting thing would be to determine why there are so many
source IDs.  What you sent me is a list of fluxes (all 0) for some of
the sources.  It would be better to look at the part that gives the
coordinates to see if the SU table shows the same coordinate for
different IDs.  Of course, WSRT data enters aips by some means over
which I have no control so this may be a "feature" of their code
rather than something substantive.  In that case, the aips task DSORC
will be of assistance to you.
