DerivationFrameworkBPhys: edit BPHY20.py, require BC candidate 3rd track to be a muon, change two variables value
This merge request edit PhysicsAnalysis/DerivationFramework/DerivationFrameworkBPhys/share/BPHY20.py for the R_Jpsi analysis. Only the value for two configuration variables were changed such that only Bc candidates with its 3rd track matched to a muon are selected. This significant reduces the DAOD size.
May I also request a new AthDerivation-21.2 cache to be prepared. Thanks a lot!
