Detailed Description

CLASSIFICATION: For each RECO Muon, match to SIM particle, and then:

If the SIM is not a Muon, label as Punchthrough (1)
If the SIM is a Muon, then look at it's provenance. A) the SIM muon is also a GEN muon, whose parent is NOT A HADRON AND NOT A TAU -> classify as "primary" (4). B) the SIM muon is also a GEN muon, whose parent is HEAVY FLAVOURED HADRON OR A TAU -> classify as "heavy flavour" (3) C) classify as "light flavour/decay" (2)

In any case, if the TP is not preferentially matched back to the same RECO muon, label as Ghost (flip the classification)

FLAVOUR:

for non-muons: 0
for primary muons: 13
for non primary muons: flavour of the mother: abs(pdgId) of heaviest quark, or 15 for tau
