Detailed Description

Configuration of gamma-hadron and pi0-hadron + isolation, correlation analysis.

Configuration macro for analysis of gamma-hadron and pi0-hadron correlation analysis both pi0 and gamma isolated or not. It does:

• Photon selection in calorimeter with AliAnaPhoton: Track matching, mild shower shape, NLM ... cuts
• Tagging of photon candidate clusters as decay from pi0 or eta or from their side bands with AliAnaPi0EbE (4 calls, one pi0, one eta, one pi0 side band and one eta side band)
• Tagging of photon candidate as isolated with AliAnaParticleIsolation
• Correlation of the photon and charged tracks, twice, one without isolation condition, and other with isolation condition
• Pi0 selection with the identification of merged clusters with AliAnaPi0EbE
• Tagging of pi0 as isolated with AliAnaParticleIsolation
• Correlation of the pi0 and charged tracks, twice, one without isolation condition, and other with isolation condition
• Optionally, the QA tasks AliAnaCalorimeterQA and AliAnaChargedParticle are executed

Main method calling all the configuration Creates a CaloTrackCorr task, configures it and adds it to the analysis manager.

The options that can be passed to the macro are:

Parameters

calorimeter	: A string with he calorimeter used to measure the trigger particle
simulation	: A bool identifying the data as simulation
year	The year the data was taken, used to configure some histograms
col	A string with the colliding system
trigger	: A string with the trigger class, abbreviated, defined in method belowSetTriggerMaskFromName()
rejectEMCTrig	: An int to reject EMCal triggered events with bad trigger: 0 no rejection, 1 old runs L1 bit, 2 newer runs L1 bit
clustersArray	: A string with the array of clusters not being the default (default is empty string)
tender	: A bool indicating if the tender was running before this analysis
nonLinOn	: A bool to set the use of the non linearity correction
shshMax	: A float setting the maximum value of the shower shape of the clusters for the correlation analysis
isoCone	: A float setting the isolation cone size
isoPtTh	: A float setting the isolation pT threshold (sum of particles in cone or leading particle)
isoMethod	: An int setting the isolation method: AliIsolationCut::kPtThresIC, ...
isoContent	: An int setting the type of particles inside the isolation cone: AliIsolationCut::kNeutralAndCharged, AliIsolationCut::kOnlyNeutral, AliIsolationCut::kOnlyCharged
leading	: An int setting the type of leading particle selection: 0, select all;l 1: absolute leading of charged; 2: absolute leading of charged and neutral; 3: near side leading absolute of charged; 4: near side leading absolute of charged and neutral
tm	: A bool to select neutral clusters as triggers
minCen	: An int to select the minimum centrality, -1 means no selection
maxCen	: An int to select the maximum centrality, -1 means no selection
mixOn	: A bool to switch the correlation mixing analysis
qaAn	: A bool to switch the calorimeter QA analysis
chargedAn	: A bool to switch the selected tracks QA analysis
outputfile	: A string to change the name of the histograms output file, default is AnalysisResults.root
printSettings	: A bool to enable the print of the settings per task
debug	: An int to define the debug level of all the tasks
