Specify which method is used to derive the relative weights of the visibilities as a function of Elevation. Mode can be

   UNIFORM   Each data point has the same weight
   AIRMASS   Weights are Airmass weighted, proportional to sin^2(Elevation)
 or
   FULL AntGain Bandwidth [Opacity]

to use a standard noise equation based on Antenna gain, Opacity, system temperature and observing bandwdith. AntGain is the Jy per K conversion factor of the antennas, and Bandwidth the observation bandwidth in MHz. Opacity is the Zenith opacity (default at start is 0.05, the value is sticky). An empirical zenith Tsys is used, equal to 0.5 K times the observing frequency in GHz.

The absolute weight can then be rescaled with a better effective noise estimate and different bandwidth using the command ADD_NOISE that also implements a proper noise generation on each visibility.
