DECONVOLVE /GAIN

            DSB2SSB\DECONVOLVE /GAIN [First_Guess]

        When this option is present, the deconvolution will try  to  adjust  the
        sideband  gains,  fitting  one  constant value per sideband for every LO
        setting.

        --> make sure you have run the deconvolution without gain fitting first!
        Here's a typical sequence of commands to turn on the gain fitting during
        the deconvolution:

          > initialize
          > deconvolve 1e-5 100 /keep
          > deconvolve 1e-5 100 /gain

        First_Guess can be set to 1 or 0.

        By default, First_Guess = 1 (the initial  guess  for  signal  and  image
        sideband gains is that they are equal to 1 for every LO setting).

        Should  any information on the sideband ratio be available in the header
        variable GAINI, the user can enforce this as initial guess for the  gain
        fitting by setting First_Guess = 0.
