Coherences
Here's a new BruCo scan for a good range time after the LSC FF improvements from yesterday:

In summary:
- no MICH coherence anymore
- a little SRCL and PRCL coherence: it might be worth trying an iterative improvement to the SRCL FF
- next in line: ASC-DHARD_Y and ASC-CHARD_P
By subtracting mostly DHARD_Y, CHARD_P, SRCL and beam jitter, we can get some additional improvement in the low frequency noise.
