Frequency averaging

Open nicholebarry opened this issue 5 years ago • 2 comments

It would convenient to be able to average the visibilities and weights as a function of frequency (i.e. go from 80kHz resolution to 160kHz resolution). There currently isn't an option to do this. However, time averaging has already been implemented, so it should be straightforward to implement frequency averaging.

When averaging flagged and unflagged channels, should be able to have the frequency array either:

  1. have the true frequency that contributed (meaning non-evenly spaced frequencies)
  2. have evenly spaced frequencies (to make it uvfits compatible)

The simple version of this was done in PR #760. More complex behavior requires fixing #759 first.
