reconstructed C angle

Comparison of the reconstructed Cherenkov angle with expected as a function of the momenum

  • geometrical reconstruction
  • x = [-10, 10] cm
  • without per-pmt/chromatic corrections

Track selection:

Only events with one track. Photon yield:

Time cut:

Cherenkov angle distribution for pions and kaons:

Cherenkov angle as a function of the momentum. Theoretically expected distribution is shown with solid line(without points):
