| 17 | 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. |
| 21 | |
| 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. |
