Detailed Description

Compact information for the generated muon pairs.

Compact information for the generated muon pairs in the MUON arm useful at the last stage of the analysis chain Pairs are built with two AliMUONTrackLight objects Using the class AliMUONTrackLight this class combines the decay information ("history") of the reconstructed tracks and fills a series of flags for the formed reconstructed dimuon: fIsCorrelated, fCreationProcess, fIsFeedDown, ... for information about the dimuon, use PrintInfo with the appropriate printflag To be used together with AliMUONTrackLight

Author: This class was prepared by INFN Cagliari, July 2006 (authors: H.Woehri, A.de Falco)
