GR cuts

Performance of the geometrical reconstruction as a function of time and Cherenkov angle- cuts .

  • CERN 18
  • S401, bar with 3-layer spherical lens
  • p/pi @ 7 GeV/c @ 20 degree polar angle
  • geometrical reconstruction
  • delta t selection with s = 0.5 ns (default)
  • with beam direction correction
  • with per-PMT Cherenkov angle correction
