Oscillations can be clearly seen starting in the 0R region, and have been there since we set up for high energy. It seems to just come with the setup we have.

Last year it was found that 0L03-7 had a similar effect on the beam, with an identical period, last run and we were unable to fix it even with a swap in the RFCM. Maybe it still is causing a problem, it is hard to tell with the information we have.

As close as we are to the end of the run, it is not worth trying to fix.
