Reconstruction efficiency for events.
Estimated reading time: 1 minuteEfficiency definition
Good candidate:
A good candidate is a MCParticle in the event that satisfies the following requirements.
- is a charged pion(PID = 211 or PID = -211)
- perp of the start vertex < 10
- prep of the end vertex > 100
Good event:
A good event is a event with no less than 3 good MCParticle candidates in it.
Reconstructed event
A reconstructed is good event with all the good MCParticle candidates reconstructed.
The definition of Reconstructed MCParticle can be found in previous section.
Efficiency
Efficiency is defined as: efficiency = #(Reconstructed events)/#(Good events)
