Minor update to truth tau building in TauAnalysisConfig
Since the primary goal is to run on DAOD_PHYS for data analysis, prefer to use AntiKt4TruthDressedWZJets
instead of AntiKt4TruthJets
(not available in PHYS), which is the current default of BuildTruthTaus from which TauTruthMatchingTool inherits.
