Variables:

          Apart from the usual imaging parameters, PIPELINE is controlled  by  a
    few variables.
      ALL%CATALOG   Spectral line catalog name (set by the CATALOG command)
      ALL%DROP[2]           Number of edge channels drop at each edge of windows
      ALL%FILTER    indicates the files to be processed
      ALL%MINFRES   (MHz) threshold in spectral resolution to separate continuum
      ALL%RANGE[3]  gives the velocity range (Vmin and Vmax) and resolution (in

      In  addition,  the self-calibration step is controlled by ALL%PHASE_NITER,
    ALL%PHASE_TIMES, ALL%AMPLI_NITER and ALL%AMPLI_TIMES that specify the number
    of Clean components and integration times for Phase  and  Amplitude  respec-
