0001 #
0002 # With this customization the ClusterizerRefinerTagMCmerged module will be substituted
0003 # for the standard clusterizer.  If a cluster is matched to more than one simTrack
0004 # its "merged" bit will be set, so that SiStripCluster::isMerged() will return true.
0005 #
0006 # If pileup is present, add the following line so that only in-time simTracks will
0007 # be counted, and make sure that process.mix is on the path.
0008 # process.siStripClusters.ClusterRefiner.associateRecoTracks = cms.bool(False)
