Minutes
- Announcements
- Reconstruction launch ver02 is bad and should not be used for DNP talks, people should use ver01 instead. This is due to problems with the track reconstruction.
- Analysis launch ver04, including the latest user plugins, was run over ver01 of the reconstructed data.
- Collaboration Meeting
- If you will not be giving a dedicated talk on your topic, then send Paul Mattione a few slides about your studies and he will include them in his overview talk.
- Beamline
- No major updates
- Tracking
- Simon showed that the problem with the reconstruction appears to be with the FDC timing offsets. The FDC timing was not used for the ver01 launch, so it was not a problem before. By hand-aligning the offsets for one file (shift by ~13ns) the p2pi yields ~double.
- When the FDC timing is calibrated and fixes to the detector geometry are included, then we'll do another reconstruction launch.
