HLT Reconstructed ESDs from Raw DAta -- Matching Residuals

Some analyzes were performed on the GRID regarding the reconstructed of the HLT chain, using the AliRoot version v4-21-32-AN, which contains the updates on the GlobalTrackMatcher.

HLTesdTree matched tracks

For the plots that will be shown later, the information was extracted in the following way:

        //Loop over the clusters, cluster number(iclus)
        AliESDCaloCluster* clus = fESD->GetCaloCluster(iclus);
        if(!clus->IsEMCAL()) continue;
        fclusE->Fill(clusterEnergy);
   Int_t nmatched=clus->GetNTracksMatched();    
        Int_t trackindex=clus->GetTrackMatchedIndex(); 
   if(nmatched>1)continue;
        if(trackindex<0)continue;
   deltaEta=clus->GetTrackDz();
   deltaPhi=clus->GetTrackDx();
   deltaR=TMath::Sqrt(deltaEta*deltaEta+deltaPhi*deltaPhi);
