APPLY

        [CALIBRATE\]APPLY [AMPLI|DELAY|PHASE [Gain]] [/FLAG [Threshold]]

      Apply  gain  solution  computed  by  MODEL and SOLVE (which are called im-
    plicitely by SELFCAL)  or obtained by READ CGAINS to the  current  UV  data.
    The  optional  arguments indicate whether this should be an AMPLITUDE, DELAY
    or PHASE gain, and what Gain value is used (in range 0 to 1). A  DELAY  gain
    is derived from a Phase self-calibration assuming the Phase errors represent
    pathlength  changes  (i.e.  delays):  phase solution is scaled with the Fre-
    quency ratio of the self-calibration and UV data to be calibrated.

      If no argument is given, the current SELF_MODE (see HELP SELFCAL) is used,
    and the gain is 1.0.

    The /FLAG option controls whether data without a  valid  gain  solution  are
    kept  unchanged  or  flagged.  You can actually flag data on this basis even
    without applying the self-calibration solution.
