18// Class for the analysis of particle - hadron correlations
19// Particle (for example direct gamma) must be found in a previous analysis
20//-- Author: Gustavo Conesa (LNF-INFN)
21
22// Modified by Yaxian Mao:
23// 1. add the UE subtraction for corrlation study
24// 2. change the correlation variable
25// 3. Only use leading particle(cluster/track) as trigger for correlation (2010/07/02)
26// 4. Make decay photon-hadron correlations where decay contribute pi0 mass (2010/09/09)
27// 5. fill the pout to extract kt at the end, also to study charge asymmetry(2010/10/06)
045396c8 28// 6. Add the possibility for event selection analysis based on vertex and multiplicity bins (10/10/2010)
29// 7. change the way of delta phi cut for UE study due to memory issue (reduce histograms)
30// 8. Add the possibility to request the absolute leading particle at the near side or not, set trigger bins, general clean-up (08/2011)
