Detailed Description

A basic pre-cluster finder.

Implementation of AliMUONVClusterFinder

This version uses a 2 steps approach :

we first clusterize each cathode independently to form proto-preclusters, and then we try to "merge" proto-preclusters from the two cathodes when thoses proto-preclusters overlap, thus ending up with preclusters spanning the two cathodes.

This implementation, on the contrary to PreClusterFinder or PreClusterFinderV2 should not depend on the order of the input digits.

Bool_t AliMUONPreClusterFinderV3::UsePad ( const AliMUONPad & pad )

virtual

Add a pad to the list of pads to be considered for clustering. Typical usage is to "put-back-in-business" a pad that was part of a previous cluster (returned by NextCluster) but was externally identified of not being part of that cluster, so it must be reuseable. Might not be implemented by all cluster finders... (in which case it must returns kFALSE)
