Minutes
- REST Production Status:
- Third run block: 10331-10913
- Completed over the holiday weekend: 2 files failed repeatedly, log files available
- Fourth run block: 11059-11346
- Calibrations complete and ready for launch, expected to complete within a week
- Third run block: 10331-10913
- Future REST production calibrations
- Expect another production before the Fall 2016 run begins, and items for improvement have been discussed at the calibration WG meetings.

- The schedule for reports on the individual reconstruction studies begins next week with:
- SC Efficiency (Mahmoud)
- CDC Efficiency (Mike)
- FDC Efficiency (Alex A.)
- FCAL Neutral Energy & Efficiency (Jon)
- The schedule for reports on the individual reconstruction studies begins next week with:
- Schedule of presentations
- Other Studies:
- A summary of rho beam asymmetry data Curtis
- Curtis prepared a document compiling the world data on the Sigma beam asymmetry for rho photoproduction.
- The uncertainties on these previous measurements are large and, as expected, aren't usable for absolute polarization normalization.
- Beam Polarization: Justin, Mike, Nathan, Richard
- The beam asymmetry observed for low energy rho production remains an open question
- Richard is looking into alternative explanations for low energy polarization, and possible improvements on the assumption used in the literature
- Ken L. added (by e-mail) that beam asymmetries using coherent bremstrahlung and laser backscattering at lower energy show good agreement, which provides some additional confidence in the CBSA method for the coherent peak region
- Note: As requested the model used for the CBSA fits is CLAS Note 2011-20 by Ken L., where the parameters in the fit are defined at the end of Sec 2 (pg 7).
- Studies are ongoing to include the tagger coincidence in the TPOL asymmetry results
- The beam asymmetry observed for low energy rho production remains an open question
- A summary of rho beam asymmetry data Curtis
- Analysis Launch Preparations:
- Plugin Requirements
- EventStore Readiness: Sean
- Work is ongoing to utilize Richard's update the HDDM interface in EventStore.
- AOB
