Weight scaling factor for the generated visibilities.
It is a relative scaling factor in the weights compared to a supposedly
optimal weighting to give the best combined synthesized beam. That opti-
mal weighting essentially gives the same weight density par unit area in
the UV plane than the shortest baselines measured with the interferome-
ter only. However, if the single-dish data has not been observed long
enough, or has baselines problems for example, this weight may add noise
to the overall data set, so could be down-weighted.
