Run3 developments for FCS Muon Punch Through

Thomas Michael Carter requested to merge thcarter/athena:mpt_add_PCA into 21.0

Containing all the developments for the Run3 developments and improvements made to the FastCaloSim Muon Punch Through tools for AF3. Contains the following:

  • PunchThroughClassifier. Calibrated classifier used to predict if an event should result in a punch through.
  • Punch through tool redesign and simplification
  • New parameterization of punch through kinematics using PCA.
  • Expands the number of punch through particle types to 9.

Supercedes !52813 (closed)

Validated using single pions. Gives significant improvement in modelling of ghost-associated muon segments (see plot).Screenshot_2022-07-04_at_15.45.09
