    1414    SamplerStatistics::
    1515      we no longer use these. So we need to avoid checking for them with CABB-type data.

    1719     Now that there are no sampler statistics, we need a different way of carrying along [wiki:Glossary/Tsys Tsys] and 
    18     [wiki:Glossary/XYPhase XYPhase] data than we have at present.
    19     At present there are 24 scalar values of Tsys (6 antennae * 2 polarizations * 2 IFs) written into every integration, and
    20     12 (6 ant. * 2 IFs) of XYPhase.

    22     In the new system there will likely be a spectrum of each, in the form of autocorrelations.
    23     Tsys is formed from the XX and YY polarisations of the autocorrelations, with the noise diode on and off;
    24     XYPhase from the XY (or its conjugate, YX) with the diode on and off.
