Removed S0 -> begins Slug 8 at run 3453 (two arms) - 3454 (R arm trips) - 3486-> good 50 uA Left arm data

I would like to arbitrarily start Slug 9 at 3520 (beam went away during 3508, 3509, and until )

Pedestals for 70 uA running (Slug 5, runs 3424 - 3432) have been recomputed and those runs are respun now (3:00 PM)
- Main det, BCMs (beamline), and SAMs all with that run range now.
- Git rm Parity/prminput/prexCH_beamline_pedestal.3425-.map
Run 3520-> starts slug 9 and has all new pedestals and even changes bcm an ds 3 for ds 1 as the normalizer -> The Pedestals have been updated from 3707321 only for bcm an ds 1x
- See commit logs and also https://logbooks.jlab.org/entry/3706784 for the status of the pedestals, they will keep changing for 50 uA running
Fully removed the BPM 4e 4a and 12 stability cuts

UPDATE

Slug 3 -> all have the wrong SAM pedestals
We need better Slug averaged plots, and Ciprian and Sakib are working on it
We have obtained plots for Slugs 1-8 using the list of parameters as it works now (~/PREX/prompt/collector/drawPostpan/drawPostPan.C(filename,descriptor,deviceList))
Right arm has been dead since run 3454 (2nd run of slug 8, and it was a needs-cuts run anyway)
FFB test during run 3486 and 3487
Runs 3489 and 3493 have some questionable regression during 1 minirun: too little data/noisy beam/FFB problems?? BPM 12 changes response after 3492
Runs 3496, 7, and 9 all have large RMS BCM noise
Runs 3498-3500 all have BPM4eX noise larger than normal
All slug 8 needed to be respun as an errant BPM 4a and 4e stability cut had been implemented, we are now needing to implement saturation cuts independently of stability cut for these BPMs (and maybe for 12 as well??)
