Hi,
Questions concerning data reduction in AIPS should normally be sent
to daip at nrao.edu. You might also ask you advisor. I'm forwarding this
to daip at nrao.edu.

> When I run TVFLG or CLIP, no FG file is added to the header, though the
> flagging is saved in the history file. I checked both by outputting the
> history file to text and looking at it, and by re-running TVFLG. When I
> run TVFLG after having 'successfully' flagged some data, the flagged
> data does not appear, but when I run UVPLT or IMAGR, the bad data is
> still there. I tested UVPLT with FLAGVER set to 0, 1, and 2 with no
> success.

> Below is an example run of my CLIP flagging, then a print of IMH after
