["Brandenburg, James" <jbrandenburg AT bnl.gov>]

Dear All,

Thank you for joining this morning. Below are the minutes for the meeting 
this morning.

Best,
Daniel

Daniel: Updates
- PR adding FST data to StEvent and StMuDst accepted and merged into DEV
- PR adding FCS WFF updates accepted and merged into DEV
- Working on  StFwdTrack Updates and ROOT geom from Jason's directions (for 
tracking in BFC)

Gavin: Tracking Alignment
- Previous result showing consistency between full & MC tracking was a 
book-keeping mismatch. Full Tracking DOES show difference compared to MC 
Tracking. MC Tracking recovers correct parameters
- Daniel and Gavin will look into possible reason that Full tracking leads to 
a bias
- Gavin will investigate the actual performance (pT res and charge ID) for 
realistic alignment case

Daniel & Flemming: sTGC Geometry
- Flemming found and fixed several remaining overlaps in sTGC geometry
- Daniel, based on suggestion from Flemming, removed all non-essential parts 
of geometry 
- move ahead with sTGC simulation and add supporting structures back

Nicole: sTGC Geometry
- Will make new material budget plots incorporating Flemmings changes and 
send to list ASAP

Discussion of EPD efficiency and tracking check
- Isaac will begin with this topic as a step towards full analysis
- The goal here is to check if the EPD efficiency is reasonable based on past 
estimates
- Second is to check how often EPD sees activity that is not reflected by FWD 
tracking - check of FWD tracking efficiency with minimal projection 
extrapolation needed

David: FCS WFF
- cross check of old vs. new algorithm
- Overall good agreement - need to check the reduced counts in pi0 peak
  - Maybe due to cut of 1 GeV for clusters -> new algo may have lower avg 
cluster energy
  - Need to run an event-by-event comparison to understand why peak is 
reduced while sidebands are not.

FCS Calibration:
- Individual calibrations are progressing. Xilin or another will summarize 
results after thanksgiving.


Rough list of items for Dec 6th Meeting:

- Gavin: Alignment
- Te-Chuan: FST QA progress
- Nicole: sTGC geometry updates
- David: FCS WFF cross checks
- Xilin or another: FCS Calibration update
- Isaac: Initial progress on analysis (EPD efficiency or J/Psi analysis)
- Xiaofeng: sTGC Timing studies
- Daniel: Tracking & Geometry updates
