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:

evtinfo
information about the event (TrkDiag/inc/EventInfo.hh)
hcnt
count of various hit types (TrkDiag/inc/HitCount.hh)
tcnt
count of various track types (TrkDiag/inc/TrkCount.hh)
de
global fit information for downstream electron track (TrkDiag/inc/TrkInfo.hh)
deent
local fit information for downstream electron track at tracker entrance (TrkDiag/inc/TrkInfo.hh)
demid
local fit information for downstream electron track at middle of tracker (TrkDiag/inc/TrkInfo.hh)
dexit
local fit information for downstream electron track at tracker exit (TrkDiag/inc/TrkInfo.hh)
detch
calorimeter cluster information for cluster used in downstream electron track fit (tch = TrkCaloHit, TrkDiag/inc/TrkCaloHitInfo.hh)
uetch
calorimeter cluster information for cluster used in upstream electron track fit (tch = TrkCaloHit, TrkDiag/inc/TrkCaloHitInfo.hh)
detsh
reconstructed straw hit information for downstream electron track fit (need diagLevel > 0, TrkDiag/inc/TrkStrawHitInfo.hh)
detsm
information about straw materials that the downstream electron track fit goes through (need diagLevel > 0, TrkDiag/inc/TrkStrawMatInfo.hh)
ue
global fit information for upstream electron track (TrkDiag/inc/TrkInfo.hh)
dm
global fit information for downstream muon track (TrkDiag/inc/TrkInfo.hh)
crvinfo
information about CRV coincidences (CRVAnalysis/inc/CrvHitInfoReco.hh)
bestcrv
???
demc
MC information about particle that created downstream track (TrkDiag/inc/TrkInfo.hh)
demcgen
MC information about particle that started the simulation (TrkDiag/inc/GenInfo.hh)
demcpri
MC information about particle that would have ultimately created the GenParticle (TrkDiag/inc/GenInfo.hh)
demcent
MC information about step of particle that created downstream track as it enters the tracker (TrkDiag/inc/TrkInfo.hh)
demcmid
MC information about step of particle that created downstream track as it passes the middle of the tracker (TrkDiag/inc/TrkInfo.hh)
demcxit
MC information about step of particle that created downstream track as it leaves the tracker (TrkDiag/inc/TrkInfo.hh)
crvinfomc
MC information about CRV coincidences (CRVAnalysis/inc/CrvHitInfoMC.hh)
detchmc
MC information about calorimeter cluster used in the downstream electron fit (TrkDiag/inc/CaloClusterInfoMC.hh)
uetchmc
MC information about calorimeter cluster used in the upstream electron fit (TrkDiag/inc/CaloClusterInfoMC.hh)
detshmc
MC information about the straw hits used in the downstream electron fit (need diagLevel > 0, TrkDiag/inc/TrkStrawHitInfo.hh)
detrkqual
the input variables and output value of the track quality artificial neural network (TrkDiag/inc/TrkQualInfo.hh)
evtwt
the values of all EventWeight objects that were in the art even (e.g. proton bunch intensity = PBIWeight)
