            CLIC\SET WEIGHTS [TSYS ON|OFF] [CALIBRATION ON|OFF]

        Selects the way the weights written in the output file  by  the  command
        TABLE are computed.

        Weights are always proportional to observing time.

        With  TSYS  ON,  data  is  also weighted by 1/TSYS**2, where TSYS is the
        equivalent system temperature (the geometrical mean of  system  tempera-
        ture of both antennas, for a given baseline). With TSYS OFF, this weight
        factor is turned off.

        With CALIBRATION ON, data is also weighted by 1/CAL**2, where CAL is the
        amplitude instrumental calibration factor (if any).  If no amplitude in-
        strumental calibration function is applied  (absolute  amplitude),  this
        weighting  should  have no effect. With CALIBRATION OFF, weights are not
        affected by amplitude calibration.

        Default is TSYS ON and CALIBRATION ON, which results in weights equal to
        1/sigma^2, where sigma is the thermal noise in the data.
