TrkAna

Overview

TrkAna is currently being developed in advance of the June 2019 Software Tutorial. This is a rough outline...

How To Run

mu2e -c TrkDiag/fcl/TrkAnaReco.fcl -s mcs.art --TFileName trkana.root

This runs two instances of the TrackAnalysisReco module. One for negative tracks (TrkAnaNeg) and one for positive tracks (TrkAnaPos).

Tree Structure

Here is a very rough description of the tree branches and where to find leaf definitions in the repository:
