Reconstruction efficiency for events.

Estimated reading time: 1 minute

Efficiency 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 is defined as: efficiency = #(Reconstructed events)/#(Good events)
