Discussion notes
Roman
- Slide 2: Kaon distributions have more background SPR plot and likelihood distribution is wider for kaon than pions. Could the timing performance still be worse for kaons than pions
- Slide 3: Preferred correction order is always to begin with per-PMT Cherenkov angle correction, since it keeps ring segments connected. Smearing by either track resolution (ring fit) or chromatic correction
- Slide 4-5: Some PMTs with bad correction, could be checked with MC
- Slide 9
