Agenda

PREX Respin

1. PREX-2 runlist spreadsheet: [1] Github repo
   • As we do the respin, the RCDB will have a new comment field that we can use to describe changes based on respin analysis
   • The entire slug 32 was mislabeled as single arm running in RCDB (and in comments), but it was actually both arm. That has been updated
2. Weibin and Tao
   • I think we're basically ready with the cuts.
3. Robert: pedestals
   • Need to check on the blinded PMT and stubby test runs
4. Victoria: beam modulation (raw data quality, residuals)
   • Paul and Victoria working to get the blessed slopes brought in as new corrector definitions for the respin
5. Move of the web directory for output plots: https://prex.jlab.org/analysis/
   • Should we have a flat structure will all runs going together, or parallel PREX and CREX structures?
     • Let's make entirely parallel structures for PREX and CREX
     • Make a web redirect from the old page to the new ones
6. Should we add the (11X+0.4*12X) combination into the respin as an event-level combination?

Analysis projects

1. Tao : additional combined plots looking at statistical self-consistency Git-repo
   • Haplog 3928 (http://ace.phys.virginia.edu/HAPPEX/3928) shows the current state of the analysis
   • Should change the pitt definition so that they only have one Wien state.
2. Weibin and Tao: table of cuts. [2]
   • Tao brings up that we should verify that the MD event cuts are set for global cuts.
3. Robert: pedestals
4. Victoria: beam modulation (raw data quality, residuals)
5. Devi: blinded tubes
6. BCM & DD resolution
   • Yufan is working on the script, but no results to show yet
7. stripline and cavity and complementary bpm resolution and performance.
   • Comparing the normal and compleemtn
   • http://ace.phys.virginia.edu/HAPPEX/3942
8. Overloaded regression (Tao?)
9. Multiplet plots: haplog3936
   • Update in http://ace.phys.virginia.edu/HAPPEX/3943. Four slugs have poor dithering corrections in the prompt results: slugs 6, 7, 39 and 72; why are their ditehr corrections poor.
