- Calibrations and detector group status reports
- TAGH and PS: Nathan has analyzed the PS skims for this run block and is studying time offsets

- Efficiency / Resolution Studies Running with this Launch
- Paul reported on the efficiency plugins which are running during the current launch, and that ROOT TTrees are being produced for these studies
- TPOL polarization update - Mike and Nathan
- Mike presented a shortened version of his talk at Monday's BLTWG meeting
- The results from Nathan and Mike's independent analyses are consistent in the range of 7.9-9.1 GeV
- There was some discussion about the comparison to the rho beam asymmetry
- Matt asked if there was a physical mechanism for fine structure in the polarization vs energy, and Richard confirmed that it could not be a crystal effect. More study is needed to see if the fine structure in the polarization vs energy is statistically significant, and if that implies some remaining systematic uncertainty
