Update TLA Pile-up residual calibration
Changes:
- Use JetPileupScaleMomentum to calculate nJet (it has been shown that is more robust in the different MC16 campaigns)
- Decorate jets with pt after jet pile-up area-based correction (which for HLT jets is pt at JetPileupScaleMomentum since no pile-up residual calibration is applied to online jets) when requested -- This is needed to calculate nJet elsewhere when an offline pile-up residual calibration is applied and hence JetPileupScaleMomentum is overwritten.
Note:
- nJet-based pile-up residual correction is only used for the TLA analysis and HLT jets
Also, remove commented code
