  [wiki:SYSCALRecordChanges]::
   The SYSCAL records will change from their current form.

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

      Deciding what to do here in terms of data representation requires discussions with WarwickWilson.
      Making changes here has flow on effects to other tasks that use Tsys or XYPhase.
+
+    ApplyingXYPhaseCorrections::
+      At present atlod applies the XYPhase during filling. Nothing else (except maybe atxy) uses them.
+      So we can compute the corrections, apply them and drop the XYPhase information, during ATLOD?
+      May need to order the RPFITS data stream so that autocorrelations come before cross-correlations
+      (and after SYSCAL records), so that the corrections for the cross-correlation can be computed
+      before reaching the cross-correlations.
