+//
+// useWeight : flag for Pt weights (default are pp 2010 weights, functions per MC production existing)
+// useFlatPtWeight : flag to test flat Pt weights (computed for LHC10f7a MC)
+// useZWeight : flag to use z-vtx weight (used for systematics for now)
+// useNchWeight : flag to use weights on the distribution of simulated primary particles (default pp 2010)
+// useNtrkWeight : flag to use weights on the distribution of Ntracklets
+// isFinePtBin : flag for fine pt bin (100 MeV from 0 to 30 GeV)
+// multiplicityEstimator : varying the multiplicity (and not centrality) estimator
+// isPPData : flag to switch off centrality checks when runing on pp data (reduces a lot log files)
+// isPPbData : Flag for pPb data, changes the Ntrk bining
+// estimatorFilename, refMult : Ntrk vs z-vtx multiplicity correction file name and average value
+// isFineNtrkBin : gives Ntrk bins of 1 unit from 0-100 (200 for pPb)
