// Class for the analysis of particle - hadron correlations
// Particle (for example direct gamma) must be found in a previous analysis
//-- Author: Gustavo Conesa (LNF-INFN)
+
+// Modified by Yaxian Mao:
+// 1. add the UE subtraction for corrlation study
+// 2. change the correlation variable
+// 3. Only use leading particle(cluster/track) as trigger for correlation (2010/07/02)
+// 4. Make decay photon-hadron correlations where decay contribute pi0 mass (2010/09/09)
+// 5. fill the pout to extract kt at the end, also to study charge asymmetry(2010/10/06)
