SET WEIGHTS

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

  Selects  the way the weights written in the output file by the command TA-
  BLE are computed.

  Weights are always proportional to observing time.

  With TSYS ON, data is also weighted by 1/TSYS**2, where TSYS is the equiv-
  alent  system  temperature  (the geometrical mean of system temperature 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 af-
  fected 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.
