Detailed Description

template<typename T>
class modules::MuonCleanerBySegmentsT< T >

Removes duplicates from a muon collection using segment references.

      This module removes duplicates from a muon collection using segment references.

      All muons that don't pass the preselection are discarded first

      Then, for each pair of muons that share at least a given fraction of segments,
      the worse one is flagged as ghost.

      Finally, all muons that are not flagged as ghosts, or which pass a 'passthrough' selection,
      are saved in the output.
