  1. PREX2 AT runs update: Ryan
    • RyR: working on respin 2 and focusing on the dithering analysis and slopes
    • RyR: the first look at the numbers it seems that the results are consistent for the most part with respin 1
    • KP: for C, Pb the corrections are small, but for the Ca40 it's 4 times the uncertainty.
    1. Respin 1
      • RyR: the Ca40 result after taking out the "frame" runs were closer to the C result
      • RyR: will update plots for regression and dithering on the min
  2. CREX AT runs update: Weibin & Robert
    • WZ: updated the Ca48 result with correct dithering slopes. We removed the problematic cycles for 2 runs and dithering and regression in good agreement. KP: we should understand what was wrong with those cycles. CC: the energy coils were not working for those. KP: we should document it (with the cycle plots).
    • WZ: a couple of other cycles show some outliers (they are still in the data). KP: you should look at the coil response in the data and see if some hardware was not working. DA: did we see such behaviour in the longitudinal running? CC: we saw some of of these in the regular running and we ended up throwing away those cycles.
  3. CREX polarimetry results: Weibin
    • WZ: got some results from Adam and Eric.
    • WZ: Compton: took one slug on each side.
    • WZ: Moller: we can use and the Feb 8th data. KP: the spread in the data is fairly large. I'll check with Eric on this.
    • WZ: remade the mul-plots for the AT runs with larger range and everything looks fine. KP: there is no correspondance between mini-run average and multiplet plots. This needs to be checked. WZ: will do. KK: We should make the DD plots to make sure that everything is ok. WZ: will do.
    • KK: we should have a table for the central values for the different quantities of interest.
  4. Spin sign matching: Robert haplog4157
    • RoR: followed the procedure outlined by Bob.
    • RoR: included halogs for the different settings.
    • RoR: I don't have the horizontal precession calculator yet.
    • RoR: I will add what the Mott results to the log.
  5. CC: aggregator is working on the ifarm with dithering information already included in the japan tree. Plots should be easier to produce.
  6. KP: how are we going to aggregate this information? CG: will set up a table and share it with everyone by the end of the week.
