8 // Class that contains the algorithm for the analysis of particle - hadron correlations
9 // Particle (for example direct gamma) must be found in a previous analysis
10 //-- Author: Gustavo Conesa (INFN-LNF)
12 // Modified by Yaxian Mao:
13 // 1. add the UE subtraction for corrlation study
14 // 2. change the correlation variable
15 // 3. Only use leading particle(cluster/track) as trigger for correlation (2010/07/02)
17 // --- ROOT system ---
