2 | // Implementation of AliComparisonDCA class. It keeps information from | |
3 | // comparison of reconstructed and MC particle tracks. In addtion, | |
4 | // it keeps selection cuts used during comparison. The comparison | |
5 | // information is stored in the ROOT histograms. Analysis of these | |
6 | // histograms can be done by using Analyse() class function. The result of | |
7 | // the analysis (histograms/graphs) are stored in the folder | |
8 | // which is a data member of AliComparisonDCA. | |
