<shortdescription>Normalize visibilities based on auto-correlations</shortdescription>
Determines the amplitude corrections neede due to errors in sampler
thresholds using measurements of auto-correlation spectra. This
correction is typically requiered for data correlated with the DiFX
correlator (such as VLBA data). Other correlators (such as the SFXC
correlator used to correlate EVN data at JIVE) already apply this
correction at the correlator. In this case, running this task is not
