- geometrical reconstruction
- with per-pmt/chromatic corrections
- [3.4, 3.6] GeV/c pions and kaons from rho and phi events
- track selection: [31,35] bars; x from [-20,20] cm range
Cherenkov track resolution for beam data as function of photon yield (resampled with 0-100% cutoff). No-constrain fit. Fitted SPR = 8.3 mrad and correlated term = 1.6 mrad.
Cherenkov track resolution for all photons (without cutoffs). Fit with Gaussian gives sigma 2.20 +/- 0.02 mrad:
