PIXSTD
Type: Adverb   (Real)
Use:  An RMS deviation about the mean image value in the units
      specified in the image header.
Null value:  none.
Verbs:
   ACTNOISE.....Puts estimate of actual image uncertainty and zero in
                header.
   IMSTAT.......Determine image statistics in rectangular area and
                return results in adverbs.
   TVSTAT.......Determine image statistics in polygonal areas set with
                the TV cursor and return results in adverbs.
Tasks:
   CUBIT........Model a galaxy's density and velocity distribution from
                full cube.
   DCONV........Deconvolves a Gaussian from an image.  PIXSTD is the rms
                level to stop the iterations.
   GAL..........Determine parameters from a velocity field.
   IMEAN........Displays the mean & extrema and plots histogram of an
                image.
   POLCO........Task to correct polarization maps for Ricean bias.
   SERCH........Finds line signals in transposed data cube.
   WARP.........Model warps in Galaxies.
