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:

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

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)

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 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)

Future Developments?

• Support for TTreeReader and RDataFrame?
