#Analysis procedure

##Remarks

• To prevent confusion, centrality bin number in the code is always 0-200 (except tagging efficiency correction functions), and shown as 0-100% only in the plotting.
• For additional help on ntuplizer see ntuplizer/README.md.
• For the additional help on the helpers and general code constructions (Draw, Fill, macro m()) , look at helpers/README.md.

• change working dir in helpers/config.h

  TString workdir = "/data_CMS/cms/lisniak/bjet2015/";
  TString tuplesfolderPbPb = workdir+"redoana/";
  TString tuplesfolderpp = workdir+"redoana/";

• create BXmistag functions:

mkdir correctionfiles
cd systematics
root -l -b -q BXmistags.C

• create trigger efficiency corrections (iterTrigEffCorr.C) and offline tagging corrections (deriveOffTagEff.C):

cd taggingcorrections
root -l -b -q  iterTrigEffCorr.C
sh runcorr.sh
cp -r tagging_jtsignal2v4_0p90/ ../correctionfiles

• tell me the truth!
  • runall.sh calculates all the xJ distributions with corrections applied for normal data (default) and smeared data (ppsmear1,2,3). You can look for distribution in results_redoana_default/xJdphi.root and mean values are stored in results_redoana_default/results.txt .
  • moneyplot.C draws a few money plots
  • plotXJ.C draws beautiful xJ distributions. Make sure it reads the right input results_*** folder!

cd asymmetry
sh runall.sh
#to check the progress
tail -f redoana_default
#after it finishes
root -l -b -q moneyplot.C\(\"redoana\"\)
root -l -b -q plotXJ.C
