Function Documentation

void ana ( Int_t mode = mGRID )

Main execution method. It:

1) loads the needed libraries in method LoadLibraries
2) depending on the files path, run etc, the variables year, collision type, data type, are obtained in methods CheckInputData and CheckEnvironmentVariables
3) put the data files in a list to be passed to the analysis frame in method CreateChain
4) In case of MC pt-Hard bin simulations, the file containing the cross sections is read and scaling parameter is obtained via the method GetAverageXsection
5) The analysis frame is initialized via de analysis manager
6) Different general analysis are initialized: Physics selection, centrality etc.
7) Specialized analysis are initialized: AliAnalysistaskCounter, AliAnalysisTaskEMCALClusterizer, AliAnalysisTaskCaloTrackCorrelations and executed for different settings.
8) The output/input containers are passed to the analysis manager
9) The analysis is executed

Parameters

mode	analysis mode defined in enum anaModes

Definition at line 86 of file ana.C.

void CheckEnvironmentVariables ( )

Access one data file and set the year, collision type and run number. It is possible to set them via external parameters.

void CreateChain	(	const anaModes	mode,
		TChain *	chain,
		TChain *	chainxs
	)

Fills chain with data files paths.

Bool_t GetAverageXsection	(	TTree *	tree,
		Double_t &	xs,
		Float_t &	ntr,
		Int_t &	n
	)

Read the PYTHIA statistics from the file pyxsec.root created by the function WriteXsection(): integrated cross section (xsection) and the number of Pyevent() calls (ntrials) and calculate the weight per one event xsection/ntrials The spectrum calculated by a user should be multiplied by this weight, something like this: TH1F *userSpectrum ... // book and fill the spectrum userSpectrum->Scale(weight)
