Detailed Description

Plot N productions comparison analysis of QA histograms from EMCal PWG-GA wagon.

Macro to plot comparison of different distributions (spectra, correlations) produced in QA trains but different data or cuts on the same data Based on the plots provided by DrawAnaCaloTrackQA.C.

*** To be completed with more cases ***

To execute: root -q -b -l DrawProductionComparison.C'("Pi0IM_GammaTrackCorr_EMCAL","AnalysisResults.root")'

The trigger name might change depending on the wagon / data type In simulations only the "default" case is available On data, there can be different triggers, depending on the period

default : min bias like triggers, kINT7, kINT1, kMB
EMCAL_L0: kEMC7 L0 EMCal
DCAL_L0 : kEMC7 L0 DCal
EMCAL_L1: kEMCEGA L1 EG1 EMCal
DCAL_L1 : kEMCEGA L1 EG1 DCal
EMCAL_L2: kEMCEGA L1 EG2 EMCal
DCAL_L2 : kEMCEGA L1 EG2 DCal A plot will be produced for each of the triggers, if they existed in the data.

void DrawProductionComparison	(	TString	listName = `"Pi0IM_GammaTrackCorr_EMCAL"`,
		TString	fileName = `"AnalysisResults.root"`,
		TString	fileFormat = `"eps"`
	)

Main method, produce the plots with the comparisons

Parameters

listName	Name of list with histograms in file (same for all productions)
fileName	File name (same for all productions)
fileFormat	define the type of figures: eps, pdf, etc.

Definition at line 112 of file DrawProductionComparison.C.

Bool_t GetFileAndList	(	TString	fileName,
		TString	listName,
		TString	trigName
	)

Access the file and list with histograms and number of analyzed events per each production.

Parameters

fileName	File name (same for all productions)
listName	Name of list with histograms in file
trigName	trigger case name

TObject * GetHisto	(	TString	histoName,
		Int_t	iprod
	)

Check if the list is available, if not get the histo directly from file

Returns: the histogram with the provided name

Parameters

histoName	histogram name
iprod	production index

void ProcessTrigger	(	TString	trigName = `"default"`,
		TString	fileName = `"AnalysisResults.root"`,
		TString	listName = `"Pi0IM_GammaTrackCorr_EMCAL"`
	)

The input files must be placed in different directories, each one defined in the string array "prod"m for ex.: TString prod[] = {"AOD142","AOD115","ESD"}; and provide a name to be used in the legeds TString prodLeg[] = {"AOD 142","AOD 115","ESD"}; Both have to be modified inside the macro.

The number of productions has to be specified const Int_t nProd = 3;
