SELFCAL /WIDGET

            SELFCAL /WIDGET

    Activates the widget interface to perform self calibration (even on spectral
    line data set). A continuum data set is extracted from the specified channel
    range, with all selected channels averaged to provide  improved  sensitivity
    to find a solution.

      The buttons control the action.
         AMPLI      Perform an Amplitude only self calibration
         PHASE      Perform a Phase only self calibration
         CHECK      Check if it makes sense
         Continue   Continue execution when the script is in Pause
         APPLY      Apply the solution
         FLAG       Flag data according to self calibration correction
         INPUT      List parameters (as in SELFCAL ?)
         SAVE       Save the parameters in selfcal.last
         SHOW       Show the computed corrections
         SUMMARY    Display the improvements in Noise & Dynamic range
