Thanks, yet again.  The actual error was that EDITA using TY tables left 
bchan=0 and echan=0.  This led the application routines to thing that 
1,0 specified something that did not apply to the current channels.  I 
fixed EDITA to set BCHAN=1 and ECHAN=Nchan.  I also fixed a bug that 
allowed an antenna with no data to be in the display list at the start.

Tomorrow's MNJ will fix.

Thanks again for your careful checking.
