=== BCMs ===
 
−
* We want to use BCM an US as our normalizer and feedback BCM
 
−
* We need to check with Hall C and turn their feedback back on when they want it (still not 100% checked out that the EPICs print for Hall C is independent)
 
−
* We need an Unser curent ramp to calibrate these at 150 uA - Caryn

=== Target/Energy Tolerances ===
 
−
* How much of a excursion is dangerous for Ca48 frame issues?
 
−
* How well centered are we on the middle of the 9.4 mm Ca48 frame? [https://logbooks.jlab.org/entry/3752440 Beam Centering and Q^2 Log entry]
 
−
* Beam Energy Fluctuation tolerances with Excited States in HRS?? - FFB fixes this? Arc 1 vs 2 energy measurements and locks?

then, to plot all combinations of alphas, deltas,and alpha/delta use the common
