[daip] Confusion with TVFLG

I have a UV database that may be multi-source (it is actually a single source, but on running FITLD it is named MULTI.SPLIT).  I use TVFLG to manually flag some times, baselines, etc., and indeed there is an FG extension added, and when I enter it back into TVFLG it can read that extension and show the correct blanked areas.  However, I think want to create a continuum file by running AVSPC.  That works, but does not apply the FG table.  I do specify FLAGVER 0, and on running, it does say UVGET: Using flag table version 1 to edit data.  I also tried UVAVG, and that also does not apply the table.  I then tried running SPLIT on the original file to create a single source data file, but I have exactly the same result.  I must be missing a key step.  How do I get the averaging routines (AVSPC and UVAVG) to honor the flagging?

We prefer daip at nrao.edu because I sometimes go on vacation.

There must be something wrong with the flags created by TVFLG.  Try 
PRTAB with INEXT 'FG' and DOCRT=1.  This will show you the full flagging 
information.  The most likely explanation is that you are not flagging 
all the spectral channels or IFs.  You can use TABPUT (verb) to fix this
channel range 0 0 is all channels.
