Changes/atlod

SamplerStatistics?
we no longer use these. So we need to avoid checking for them with CABB-type data.
XYPhaseCalibration?
instead of a single (instrumental) XY phase term, we will now get all the autocorellations. This has the potential to greatly inflate the data volume.
IdentifyParentWindow?
Each spectral window output by the correlator can have some ZoomBands? defined. We think that it will be necessary to keep track of each window's parent window. There should only be 0 or 1 parents.

Whether it is necessary to keep track of the children of a particular band is unclear.

FlaggingWithinATLOD
atlod? does a qualitatively different type of flagging to other parts of Miriad; it drops data from the output instead of just marking it as bad.

There are two possible types of flagging-related changes.

  • removal of birdies - there are likely to be some new ones
  • possibly using the autocorrelations? to flag data affected by interference.
