Detailed Description

Create signature for "physical" event (check numFeatures()>0 to recognize "physical" event afterwards).

Tries to filter real physical event (i.e. the one which triggered) by applying following criteria:

• discard events without beam particle entirely
• only take into account tracks which have
  • associated particle
  • defined momentum
  • at least one vertex
