Detailed Description

This class takes the tracker muons (which are reco::Muons) and creates the correspondent reco::RecoChargedCandidate.

Intermediate step in the L3 muons selection. This class takes the tracker muons (which are reco::Muons) and creates the correspondent reco::RecoChargedCandidate.
