Bhabha and Dimuon control samples (II)

The postscript file for this page can be found here.

The plots drawn on this page are the following.

• Top left
  This plot shows the θ_C resolution (in rad.) per BhaBha track.
• Top middle
  This plot shows the distribution of the number of PMT hits associated to Bhabha tracks.
• Top right
  This plot shows the distribution of the number of expected photons per Bhabha tracks.
• Bottom left
  This plot shows the θ_C resolution (in rad.) per di-muon track.
• Bottom middle
  This plot shows the distribution of the number of PMT hits associated to di-muon tracks.
• Bottom right
  This plot shows the distribution of the number of expected photons per di-muon tracks.

• For Bhabha events, there are more hits associated in average to real tracks than to simulated ones. This is due to an imperfect match between data and simulation.
