    2121 12 (6 ant. * 2 IFs) of XYPhase.[[BR]]
    2222 [[BR]]
    23  In the new system there will likely be a spectrum of each, in the form of autocorrelations.
    24  Tsys is formed from the XX and YY polarisations of the autocorrelations, with the noise diode on and off;
    25  XYPhase from the XY (or its conjugate, YX) with the diode on and off.[[BR]]
    26  [[BR]]
    27  Deciding what to do here in terms of data representation requires discussions with WarwickWilson.
    28  Making changes here has flow on effects to other tasks that use Tsys or XYPhase.
    2923 CABB data will include autocorrelation for both ON and OFF phases of the switched noise diode.[[BR]]
    3024 ATLOD will calculate[[BR]]
    … …  
    3529   XYPhase(f) = arg( XYPhase_ON(f) - XYPhase_OFF(f) )[[BR]]
    3630 ATLOD will record in the Miriad data TsysXX(f), TsysYY(f) and XYPhase(f).
    37  Input option 'noauto' will determine whether autocorrelation spectra are kepts.
     31 Input option 'noauto' will determine whether autocorrelation spectra are kepts.[[BR]]
     32 Deciding what to do here in terms of data representation requires discussions with WarwickWilson.
     33 Making changes here has flow on effects to other tasks that use Tsys or XYPhase.[[BR]]
    3834 ApplyingXYPhaseCorrections::
    3935 ATLOD applies the XYPhase correction, but retains the XYPhase(f) spectrum in the output.
