Pedestal/Calibrations Updates
In order to salvage current ramps and trips on large chunks of data and save time/save the regression/pedestal usefulness:
- Change the lower limit current cut to be nominal-15 uA (35 for 50 uA, 55 for 70 uA)
- Updating the event cuts to have nominal-15 uA beam current lower cut Starting at run 3456 (now) and also setting specifically for 3 70 uA current ramp runs 3424, 3429, 3430 (suspect Aq, but worth a try)
- 50 uA: prexCH_beamline_eventcuts.2948-.map -> prexCH_beamline_eventcuts.3456-.map
- 70 uA: prexCH_beamline_eventcuts.2948-.map -> prexCH_beamline_eventcuts.[3424,3429,3430].map
