TVRESID
Type: Verb
Use:  TVRESID will display the residuals of a slice and a model file
      directly to TV graphics plane without going through a plot file.
      It erases the specified graphics plane, labels the plot, and
      then draws the slice residual (slice - model) data.  TVARESID
      draws slice residuals without the erasure and labeling.

      Usage hint:  Start with a TVINIT to clear the TV memory.  Then
      do a TVSLICE to one graphics plane, TVAMODEL and TVARESID to two
      other graphics planes.  This allows all three to be seen but in
      different colors to aid recognition.  When one or more of the
      plots overlap additional complementary colors are used.  One of
      the parts of this display may be replaced with GRCLEAR and a new
      TVAMODEL or TVARESID without deleting the other parts.  GROFF
      will make one part invisible without deleting it.
Adverbs:
  INNAME......Image name (name).        Standard defaults.
  INCLASS.....Image name (class).       Standard defaults.
  INSEQ.......Image name (seq. #).      0 => highest.
  INDISK......Disk unit #.              0 => any.
  INVERS......Version # of SL file.     0 => highest version #
  IN2VERS.....Version # of model file.  0 => last version.
  LTYPE.......Labelling type, see HELP LTYPE for details:
              1 = border, 2 = no ticks, 3 or 7 = standard, 4 or 8 =
              relative to ref. pixel, 5 or 9 = relative to subimage
              (BLC, TRC) center, 6 or 10 = pixels.  7-10 all labels
              other than tick numbers and axis type are omitted.
              Add n * 100 to alter the metric scaling.
  PIXRANGE....Min,Max of Image intensity.  0 => entire range of
              the slice (not the image).
  BDROP.......No of slice pts to omit from beginning of plot.
  EDROP.......No of slice points to omit from end of plot.
              Note that these are points in the slice not pixels in
              the original image.  Use INEXT='SL'; EXTLIST to see how
              many points are in the slice.
  GRCHAN......TV graphics plane to use.  <= 0 -> 1
