HELP SECTION

BSTST
Task:  Test correction of freq-switched data.  The EKH solution is
       performed and, optionally, a Clean solution is also performed.
Adverbs:
  IMSIZE.....Number of channels, (2) ignored
  BCHAN......First channel actually observed
  ECHAN......Last channel actually observed
  NGAUSS.....Number components (1 - 4)
  GMAX.......Peak values
  GPOS.......(1,n) channel of peak, (2,n) ignored
  GWIDTH.....(1,n) FWHM in channels, (2,*), (3,*) ignored
  DPARM......Throws to try in channels, 0 ends list
             -dparm(j)/2 used for plus, +dparm(j)/2 used for minus
  FLUX.......Noise to add: <= 0 => none.  This is the noise added to the
             difference spectrum.  Each separate spectrum therefore has
             FLUX/sqrt(2) as the rms noise.
  FACTOR.....Compute the spectra with throws FACTOR * DPARM(i), but
             solve them witb throws of DPARM(i).  0 => 1.
  PRTLEV.....Prints only those channels for which the reconstructed
             spectrum differs from the model by more than PRTLEV.
             No default.
             < 0 => do plot rather than print
  NITER......Clean iterations.  0 -> No Clean solution.
  GAIN.......Loop gain in Clean
  INNAME.....File to which to attach plot file (name)
  INCLASS....File to which to attach plot file (class)
  INSEQ......File to which to attach plot file (seq #)
  INDISK.....File to which to attach plot file (disk)
  XYRATIO....Ratio of X to Y.  0 -> 1.  Values larger than 1 spread
             the plots in the Y direction.
  DOTV.......> 0 => plot on TV, else make plot files
  GRCHAN.....Graphics channel for plot
