HELP SECTION

PBSIZE
Type:  Adverb  (array(64))
Use:   Gives the primary beam size (FWHM in arc seconds) for up to 64
       fields.  < 0 => not an interferometer image, > 0 an
       interferometer image with a Gaussian primary beam (VLA beam is
       substituted where appropriate)

       Also used where a large array is needed.
Null value:
       0 => no corrections
Tasks:
   FIXBX.......Converts a BOXFILE to another for input to IMAGR.  PBSIZE
               is misused to give the old DECSHIFT values.
   LTESS.......Makes mosaic images by linear combination.
   REAMP.......Scale visibility amplitudes by IF- or subarray-dependent
               factor.  PBSIZE is misused to give up to 64 scaling
               factors.
   REWGT.......Modifies UV data re-scaling the weights only.  PBSIZE is
               misused to give up to 64 scaling factors.
   STESS.......Finds sensitivity in mosaicing.
   UTESS.......Deconvolves polarization images by maximizing emptiness.
   VTESS.......Deconvolves sets of images by the Maximum Entropy Method.
