FLAG

            SELFCAL FLAG [Threshold]

        Flag  data  which  have  no  valid correction, or a correction above the
    specified Threshold (in degrees, > 0 for PHASE, no units, >  1  for  AMPLI).
    The mode (AMPLI, PHASE or DELAY) is taken from the default mode 'SELF_MODE'.
    No correction is applied however.

        With the Widget interface, no Threshold can be specified.
