• Kent and Joachim don't have progress on the detector correlation work this week
  • Kent is starting to do some pivot toward the panguin functionality and thinking about plotting
  • Joachim is working through the code to understand the japan framework a little better, and considering possible additional comments
• Juliette had been starting work to get realistic rates and asymmetries in for the detector tiles, even without correlations. Prakash will reach out to make sure Juliette has the most up to date values for the rates and asymmetries.
• Status of the ET support classes
  • The ET classes in japan-MOLLER have been tested
• Chandan doesn't have a update on
  • The basic FADC and GEM decoding is available. Four detector classes are planned (thin quartz, scintillator, shower max, )
  • They have had a discussion about how to associate the GEM tracks to the detector elements, and decided it makes most sense to not try to do that internally to the analyzer, but to do it with scripts from the results in the root files
• Dustin brings up a discussion from the detector meeting earlier today, that we need to make sure we advertise the naming and numbering scheme
  • Related to that, he also asks how will will be handling the various detector mapping and parameters. Japan uses ASCII files for all that; do we want to continue using that, and if so do we want to develop tools to help us validate those files other than using the analysis
  • Possibly both of these need a small-group meeting.
• We should start discussing how the physics asymmetry would be blinded
  • Kent reminds me that we had a preliminary discussion a year or so back; we should revisit this, and involve other groups in those discussions
    • The basic concept is an additive blinding term which is weighted differently for each type of tile based on the expected background dilutions
  • Dustin comments that we'll want to make sure that the blinding doesn't disrupt the various tests we would want to do
  • Kent and Paul think that the concept shouldn't impact the various tests, but we should be sure to do testing of the scheme to ensure we don't blind things we don't mean to blind, and that the blinding doesn't get spoiled by doing the tests.
