- Combine the MC label determined during the reconstruction and the one obtained by comparing clusters and trackRefs positions to assign the final label. - Identify the tracks build up from a decay chain in the spectrometer and set the MC label to the ID of the most downstream detected daughter. - Use the bit 22 of the AliESDMuonTrack (esdTrack->SetBit(BIT(22), kTRUE)) to identify tracks associated to decay chains. - Use the bit 23 of the AliESDMuonTrack to identify tracks associated to MC tracks or decay chains that are not reconstructible (contain not enough hits to fulfill alone the tracking criteria).
