Agenda

1. PREX respin2 preparation: merging changes
   • Finishing normalzing BCM change. New variable link to target normalizing bcm is added for residual test and unnormalizing
   • Pedestal updates ready
   • Added new target positions (uncorrelated) in combiner, but should not be used in grand correlator.
   • Added AT in global error event cut
   • Opening burp cut in BPM NOT merged in yet. Final report on next Wednesday meeting (Victoria)
   • Additional correlator with SAM included. Already exists with standard BPM sets.
   • Slow control variables added in slow tree.
   • ifarm job submission. ( Robert R / Sakib R )
   • tiny short run can be discarded by aggregation
   • Use japan internal burst counter for minirun definition. Minimum length is 9000 patterns and the maximum length will be less than 9000*2 patterns.
2. CREX related changes
   • pedestal updates
   • dithering run ranging : using prompt definition
   • discussing whether we should open burp up in CREX
3. Transverse data set
   • RyR: PREX respin1 plots are all ready
   • CP: updated pedestal in google sheet. PK: pedestal changes should already be included in respin2
