Agenda

Attending: Sean (NU); Mike S., Will M., Naomi (CMU); Andrei (Regina); Matt S. (IU); Simon, Lubomir, Adesh, Beni, Alex B., Alex A., Mark I., Justin, Nathan, Eugene (JLab)

1. Announcements came at the end of the meeting this time
2. Calibration Updates
   • We reviewed the current status of calibrations for the next set of production runs (runs ). Mike is adding some better CDC calibrations today, and Nathan finished up this morning. Sean and Justin will check these and give their OK.
   • We then discussed the status of calibrations for the 3rd set of production runs (runs 10331 - 10913). These runs have been mostly calibrated, the issues left to do are:
     • Alex B. is double checking the TAGM calibrations for any lingering issues
     • Adesh is checking the non-linear corrections.
     • Nathan and Sean will discuss offline a plan for attacking the TAGH calibrations.
     • Naomi will work on the CDC gains. These are correlated with temperature and pressure in the CDC. These conditions varied over a larger range in these earlier runs, so she will need time to make sure her parameterization works for these runs.
     • We agreed on a deadline of next Friday for these calibrations, and to check the progress of these calibrations at the Analysis meeting next Tuesday.
   • Calibration Plans for Second Production Run
3. Simulations
   • sim1.1 for data/simulation matching studies
     • Finishing preparations: update plugin list, wait for Adesh's FCAL updates
4. AOB
