21.4 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
