    Stability Threshold for flagging data after Self-Calibration.

    For Self-calibration solutions with more than one iteration, the solution is
    flagged if the difference between the last two iterations exceeds  Threshold
    times the expected phase error due to noise.

      The default is 0, a convention indicating to ignore this flagging step.

      When  the  noise  level  is appropriately estimated, a Threshold of 3 is a
    good value to suppress unstable solutions that reflect some  issues  in  the
    self-calibration model.
