UVTAPER   LLLLLLLLLLLLUUUUUUUUUUUU CCCCCCCCCCCCCCCCCCCCCCCCCCCCC
----------------------------------------------------------------
UVTAPER
Type:  Adverb (Real array, 2 elements)
Use:   Specify widths in U and V directions of Gaussian function
       used to weight down long baseline data points.  Units are
       distance to 30% point of Gaussian in kilolambda
Null value: 0
       Null value means do not taper.
Verbs:
   OBITIMAG......Access to OBIT task Imager without self-cal or peeling.
   OBITMAP.......Simplified access to OBIT task Imager.
   OBITPEEL......Access to OBIT task Imager with self-cal and peeling.
   OBITSCAL......Access to OBIT task Imager with self-cal, NOT peeling.
Procedures:
   CXPOLN........Procedure to make complex polarization images and beam.
   LINIMAGE......Build image cube from multi-IF data set.
   MAPPR.........Simplified access to IMAGR.
Tasks:
   HOLGR.........Read & process holography visibility data to telescope
                 images.  UVTAPER gives the type and size of a tapering
                 function applied during gridding.
   HOLOG.........Read & process holography visibility data to telescope
                 images.  UVTAPER gives the type and size of a tapering
                 function applied during gridding.
   IM2UV.........Converts an image to a visibility data set.  UVTAPER
                 is applied to the weights not the data.
   IMAGR.........Wide-field and/or wide-frequency Cleaning / imaging task.
   SCIMG.........Full-featured imaging plus self-calibration loop with
                 editing.
   SCMAP.........Imaging plus self-calibration loop with editing.
   UVMAP.........Makes images from calibrated UV data.
