If you run TVFLG on the calibrators, you need to be carefule to have it
flag ALL-SORC (all sources) and to include the times of the target
sources - i.e. flag from the 1 cal scan through the next or whatever.
Try PRTAB on the FG table and see if the source column is not 0 - 0
means all, otherwise a specific source is selected.
