void AliTrackletAODdNdeta::SetAbsMinCent ( Double_t x = -1 )

inline

Set the very least centrality to consider. This is for cases where the centrality calibration of simulated data doesn't really match the real-data one, but we want to keep the original centrality bins. E.g., for LHC15k1b1, the calibration of the DPMJet centrality does not give the same mean number of tracklets for the very most central bin. We therefor need to rule out the event with a very large number of tracklets from the sample by setting this parameter to for example 0.1. If this parameter is set to a negative value (default) it is not considered.

Parameters

x	Absolute lowest centrality to consider
