I have been away on vacation.

1. IMAGR does not contain any option to FLATN since that may or may not 
be desirable.

2. AIPS has no joint deconvolution (mosaicing) algorithms.  You can run 
IMAGR separately on the pointings and then use FLATN (NMAPS in addition 
to NFIELD fields per pointing).  High dynamic range mosaicing is an 
algorithm that has not been solved by anyone so far as I know.
