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