class AliBackgroundSelection: public AliAnalysisCuts
AliBackgroundSelection This class implements to cuts to reject background events from the samples to be used in the physics analysis: 1. A linear cut on the correlation cluster vs tracklets 2. A cut on the delta phi window used by the vertexer Z The parameters used in both cuts can be set The class also produces control histograms for all and accepted events, for each trigger class present in the data independently. Histograms are booked on the fly in the UserExec, whenever a new trigger class is found. After the first implementation, it was realized that the deltaphi cut is more a quality selection cut than an event selection cut, so it is effectively disabled by default.
