backward reconstruction

TOF of the particles as the function of likelihood selection of the geometrical reconstruction.

  • CERN 18
  • run 403, 7 GeV/c pi/p @ 20 degree polar angle
  • geometrical reconstruction
  • delta t selection with s = 0.5 ns
  • Cherenkov angle selection = 50 mrad
  • with beam direction correction
  • with per-PMT Cherenkov angle correction
