There are four executables ( all in ZJetBalance/util ): runZBJetBalance - Process xAOD with basic object/event selection after object calibration and writes out small analysis NTuple runProcessZJetBalanceMiniTree - last of object/event selection and fills histograms ZJetBalancePlotter - run the JES_ResponseFitter/ and evaluate the JES response function drawZJetBlanace - run final plotter

Then to run an example xAOD to make an NTuple :

runZBJetBalance -inFile /afs/cern.ch/user/g/gfacini/public/mc15_13TeV.361107.PowhegPythia8EvtGen_AZNLOCTEQ6L1_Zmumu.merge.DAOD_SUSY5.e3601_s2576_s2132_r6633_r6264_p2370_tid05768578_00/DAOD_SUSY5.05768578._000001.pool.root.1

The output tree is in submitDir/data-tree/.

Then, the next step is to fill histograms from the output NTuple

runProcessZJetBalanceMiniTree -inFile /eos/atlas/user/o/okumura/data/ZBJetBalanceStudy_v20150807/mc15_13TeV_50ns/mc15_13TeV_50ns_361107 -submitDir submitDirZMC

runProcessZJetBalanceMiniTree -inFile /eos/atlas/user/o/okumura/data/ZBJetBalanceStudy_v20150807/data15_13TeV_50ns -submitDir submitDirData

# do hadd
rm -f ZmumuAll.root
hadd ZmumuAll.root submitDirZMC/hist-user*.root

rm -f DataAll.root
hadd DataAll.root submitDirData/hist-user*.root

Then the output histogram will be fed into the final JES_Response_Fitter tool as following.

ZJetBalancePlotter -inFile ZmumuAll.root -outTag ZmumuAll

ZJetBalancePlotter -inFile DataAll.root -outTag DataAll

Then you will get the following four files.

Zjet_DB_Gauss_fits_ZmumuAll.pdf
ZJetBalancePlotterOutZmumuAll.root
Zjet_DB_Gauss_fits_DataAll.pdf
