Data taken in C, S, and L bands by the full 10 antenna VLBA on 03jul2014 suffer from ripples in both amplitude and phase for both cross- and auto-correlations for BR in LL only. Attached are two POSSM plots that show this. It happens all through the experiment and at all bands. No other stations appear to be affected.

Jon Romney told me how to handle this a couple of years ago but sadly I have forgotten...

Thanks for your help,

Dave
