SELFCAL

            SELFCAL [?|AMPLI|APPLY|PHASE|SUMMARY|SHOW [Last [First]] [/WIDGET]

      Command to perform Self Calibration (even on spectral line data, and  even
    on  Mosaics since Version 3.6 -- Jul-2023).  The solution is computed, saved
    and/or applied. SELFCAL encapsulates the use of commands from the CALIBRATE\
    language to provide a more user-friendly approach to self-calibration.

      The arguments control the action.

        SELFCAL ?        Lists the self calibration parameters
        SELFCAL AMPLI    Compute an Amplitude only self calibration
        SELFCAL APPLY    Apply the computed solution
        SELFCAL CHECK    Check if Self-Cal makes sense
        SELFCAL FLAG []  Flag data according to self calibration correction
        SELFCAL PHASE    Compute a Phase only self calibration
        SELFCAL SHOW []  Show the computed corrections
        SELFCAL SAVE     Save self calibration parameters in selfcal.last
        SELFCAL SUMMARY  Display the improvements in Noise & Dynamic range
                         and calibration status
