Detailed Description

Calculate Chi2 distributions for different cluster parameters.

Take the output distributions of CompareDataAndNMCProdPerSM.C and calculate the Chi2 distribution provided a "data" distribution reference compared to multiple MC distributions. See how to execute it in MakeDataMCComparisonPerSMClusterEbinAndChi2.C. Calculated Chi2 histograms stored in output file for further processing and calculations.
