    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.
