To do list from last meeting
- Next Steps:
- look at the a2 mass peak - adjust cuts on the eta and pi0 masses
- introduce Pythia background - skim off the wanted events by cutting on the total neutral energy (but we need to record the total number of events before skimming) - hd_filter is a good program example
- cut on eta and pi0 masses, then look at the effect on the different angular distributions (i.e. Gottfried-Jackson angles, etc.)
- look at difference between reconstructed and generated z position for less than 65 cm
- look at single photon reconstruction efficiencies
- adjust the error matrix for the BCAL (look in PID/DPhoton_factory.cc)
Documents to Review
Tentative Agenda
- Status quo on where we left off (Blake)
- Discussion (all)
Minutes
Attendees: Matt, Ryan, Mihajlo (IU), David (Jlab), Blake, Zisis (UofR)
- Blake reports:
- updated the calibration in the repository (includes dark rate)
- the pi-0 work is currently on hold
- has had some problems with the new ROOT version on the IU cluster
- Matt briefly discussed the 7x7 error matrix with the variance along the diagonal and covariant elements off diagonally. The work depends on a coordinate transformation from local to global system.
- Blake will review all relevant documents on the portal, starting with the Software section of the Calorimetry Review (GlueX-doc-989 Calorimeter Simulations)
