A bit more information, perhaps useful.  When Barry finished,
I asked the operator to revert to one subarray using Xsysstart.
When he had done so idcaf and the correlator had different
ideas about what they were doing: idcaf wrongly expecting mode
1A line data while the correlator was in continuum.  Restarting
the script brought all into order.
