INPUTS

NGAUSS          0.0         4.0    No of Gaussian components.
         @          Output adverbs
GMAX     @                         Max value of the components.
GPOS     @                         Positions of the components.

HELP SECTION

TVSET
Type: verb
Use:  To allow interactive setting of parameters for 1D Gaussian
      fitting (slices) by using the TV cursor.  The slice to be fitted
      must have already been plotted on the TV graphics screen.  Move
      the TV cursor to the specified points and press any button (A,
      B, C, or D) to enter the parameter.  Instructions will appear on
      your input window.

      TV1SET n allows only component n to be set.
Adverb:
  NGAUSS......The number of gaussian components (1 through 4).
Output adverbs:
  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 ??).
