Description
Invert with options=systemp uses noise weighting of the visibilities for optimal signal to noise in the image.
With CABB, we need to update the algorithm to take into account the way Tsys is calculated (spectrum of values) and the channels overlap in the 2GHz band.

The fsystemp option has been implemented, this requires data with autocorrelations and running atrecal to compute the tsys spectrum
