Good - Run 5477 - Ca48 150uA - Cut out the first 45k events due to strong beam instability
Good - Run 5478 -

Slug 104 has FFB turn on mid way through the slug - this makes the optics/energy in the HRS more comfortable and stable
SAM 7 is updated and ATs are moved at the end of slug 103 and ATs are moved at the end of slug 104, so these are bifurcations
Fixed the prompt summary to report correct number of patterns: https://logbooks.jlab.org/entry/3753878
12X energy shifting
- Dispersion in the arc is measured as 0.4 MeV/mm
- Dispersion in the HRS is 6.2 mm/MeV
- Dithering does a 0.5 mm p2p fluctuation in 12 X -> 1.25 mm shift in the HRS Quartz
- Normal running without FFB does 1 mm p2p fluctuations (over hour time scale) -> 2.5 mm shift in the HRS quartz

The AT combos of interest are Ldd avg Rdd (for vertical transverse), Indd avg Outdd (most important for horizontal transverse), and dd's therein

-Running the BeamMod analysis for a single run.
-From ~/PREX/prompt/bmodAna/
-create a new beammod root file from the already prompted run (####) using command
