Performance and calibration studies for run 401 (high statistics).
- CERN 18
- S401, bar with 3-layer spherical lens
- p/pi @ 7 GeV/c
- geometrical reconstruction
- delta t selection with s = 0.5 ns
- with beam direction correction
- with per-PMT Cherenkov angle correction
Performance for the run 401 with comparition to run 403.
