18 // Count events with different selections
20 // It produces a histogram with the number of events with 9 bins:
21 // 0: all events (that passed the physics selection if it was on)
22 // 1: same but cross check that event pointer did exist
23 // 2: passes vertex cut
24 // 3: passes track number cut, tracks for eta < 0.8
30 // 9: not pileup from SPD
35 // 14: 10 && 2 && 3 && 5
