Function Documentation

void ana

(

anaModes

mode = mLocal

)

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/EMCal correction framework, 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

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)
