GPOS
Type: Adverb   (Real(2,4))
Use:  An array, dimension (2,4), containing the initial guess of the
      (X,Y) pixel value of the position of a component.  fOr
      1-dimensional fitting the X values are the only ones  used. Up to
      four components can be entered.  The units for slice fitting
      depend on LTYPE (use TVSET).
Null Value: None
Verbs:
   MFITSET.......Gets adverbs for running IMFIT and JMFIT.
   SET1DG........Verb to set 1D gaussian fitting initial guesses.
   TK1SET........Verb to reset 1D gaussian fitting initial guess.
   TKAGUESS......Verb to add a plot of the slice model guess directly on
                 TEK.
   TKGUESS.......Verb to display slice model guess directly on TEK.
   TKSET.........Verb to set 1D gaussian fitting initial guesses.
   TV1SET........Verb to reset 1D gaussian fitting initial guess on TV
                 plot.
   TVAGUESS......Verb to re-plot slice model guess directly on TV
                 graphics.
   TVGUESS.......Verb to display slice model guess directly on TV
                 graphics.
   TVSET.........Verb to set slice Gaussian fitting initial guesses from
                 TV plot.  Highly recommended to get the units right.
Tasks:
   BSMOD.........Creates single-dish UV beam-switched data with model
                 sources.
   BSTST.........Graphical display of solutions to frequency-switched
                 data.
   IMFIT.........Fits Gaussians to portions of an image.
   JMFIT.........Fits Gaussians to portions of an image.
   SDMOD.........Modifies single-dish UV data with model sources.
   SLFIT.........Task to fit gaussians to slice data.
   UVFIT.........Fits source models to uv data.
   UVGIT.........Fits source models to uv data.
