Review of minutes from the last meeting
We went over the minutes from the meeting on November 29th.
- We have not had further word on the reports of disagreement between data and MC for timing signals timing signals from the FCAL.
- Data/MC discrepancy in FCal Matching around Beam Hole. We went over this issue nearly from beginning to end to refresh our collective memories. Sean is planning to look at an event sample from Rebecca Barsotti with exclusive ω events for hits in the FCAL (a) near the beam hole and (b) not from the detected proton or particles from ω decay. These may be different than the real data events Alex shows in the issue.
- Crash adding daughters on RHEL/CentOS 8. Hao Li closed this issue.
- Add incident angle dependence to DIRC mirror reflectivity. No new news on this one.
Issues on GitHub
There were no new issues other than the ones noted above.
Sean mentioned an emerging issue with timing for CPP. Sean asked Elton Smith for a sample of signal Monte Carlo (&mu pairs were provided) to work out the timing calibration procedure without use of the start counter. Some development was needed to get everything working. And yet, after calibration constants are applied, the vast majority of events show a 4 ns offset from the correct RF time. He is waiting for feedback from Elton and Simon, but this may show up as an issue in the future.
