[daip] Possible to reduce size of HI table?

[Alan Marscher]

Hi,

Some of our VLBA images have extremely long history tables that
cause long load times when we make movies of sequences of images.
Is there a way to reduce the size of the HI table so that it
only contains what is necessary to process the image. I.e., we'd
like to delete all the records about the various AIPS tasks that
were run to get to the image. I couldn't find any obvious way to
do this in the FITTP explain file or in the list of verbs.

Thanks 10**6,
Al
