Detailed Description

This processor make a MET selection (selection code provided by Patrice Verdier).

Usage: add this processor to the controller Run processor, e.g.
cafe.Run ... METSelector(processor_name) ... You can change default behavior via configuration file.

Optional parameters (negative values or 0 means no cut):

• .From: brunch with MET [default: "Met"]
• .minMET: upper cut on MET (MET > minMET) [default: 0]
• .maxMET: lower cut on MET (MET < minMET) [default: 0]
• .minSET: upper cut on SET (SET > minSET) [default: 0]
• .maxSET: lower cut on SET (SET < minSET) [default: 0]
• .jetAlgoType: type of jet algo JCCB (0.5 cone) or JCCA (0.7 cone) [default: "JCCB"]
• .jesMuCorrected: use JES corrected for muons or not [default: false]
• .MuCorrected: use MET corrected for muons or not corrected [default: false]
• .MCsmeared: use MC smearing correction to MET. Will be applied only to MC [default: true]

METSelector will put the MET information to the event. You can access it as
event.get("caf_util::MET", met) ;
event.get("caf_util::SET", set) ;
event.get("caf_util::METx", metx) ;
event.get("caf_util::METy", mety) ;

Some comments about coherent use of JES and MET muon corrected (from mail exchange with Patrice Verdier)

• If you use JES without muon correction (".jesMuCorrected false") you can use MET corrected with muon or not (".MuCorrected false or true").

• If you use JES with muon correction (".jesMuCorrected true") you must not use MET with muon correction (".MuCorrected true") because of the double counting of muons matched with Jets. In that case you must use MET without muon correction (".MuCorrected false"). You can correct this missing ET by yourself for the muons not matched with good jets.
