- LUT comparisons (files are located at /group/halld/Users/jrsteven/2018-dirc/):
- lut_commissioning_2019_v10.root, (default) what's in CCDB with the “nominal” geometry and photons generated over the full end of the bar surface
- lut_commissioning_2019_v12.root, Yunjie’s “as-built” geometry with photons generated over the full end of the bar surface
- lut_commissioning_2019_v13.root, Yunjie’s “as-built” geometry with photons generated from the center of the bar end only (ie. DIRCLUTSPREAD=0)
- LED data analysis and comparison to laser test stand data Plots (Bill/Andrew)
- REST file processing (ver08) just completed for all commissioning runs with beam 60700-60883:
- Software/simulations
- Realistic efficiency/time resolution implemented in DIRCSmearer and merging with random hits added: current branch on GitHub (Justin)
