TV1SET: Verb to reset one of 1D Gaussian fitting initial guess.

INPUTS

              Uses immediate argument: TV1SET n
                 to reset component n
         @       Output adverbs
GMAX     @                         Max value of the components.
GPOS     @                         Positions of the components.
GWIDTH   @                         Width at 1/2 max amplitude.

HELP SECTION

TV1SET
Type: verb
Use:  To reset parameters of one component for 1D Gaussian fitting
      (slices) by using the TV cursor.  The slice to be fitted must
      have already been plotted on the TV screen.  This verb uses an
      immediate argument to determine which component to set.
      Example:
            TV1SET(3)
      to reset component 3.  Move the cursor to the peak of component
      n and press any button and then move it to the horizontal
      position of the half-power point and press any button.
      Instructions will appear on yopur input window.

      TVSET will do all NGAUSS components.
Output adverbs:  Only the n'th component will change.
  GMAX........Initial guess of maximum amplitudes.
  GPOS........Initial guess of positions of the components in
              GPOS(1,i).  GPOS(2,i) not used.
  GWIDTH......Initial guess of widths at 1/2 max amplitude in
              GWIDTH(1,i).  GWIDTH(2,i) and GWIDTH(3,i) are not used.
              Note that the units of GMAX, GPOS, and GWIDTH are those
              in the plot (e.g. mJy, arc sec or Jy, degrees or ??).
