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.
