Detailed Description

This produces a reco::MET object that stores MHT (or MET)

Author

Steven Lowette

Michele de Gruttola, Jia Fu Low (Nov 2013)

MHT (or MET) is calculated using one of the input collections:

• Calo or PF jets
• tracks
• PF tracks
• PF charged candidates
• PF candidates MHT can include or exclude the contribution from muons.
