Detailed Description

ReComputeMET recomputes missing corrections. It doesn't change the overall sum of cell energies and recompute corrections only for a given jet algorithm type (ie. JCCA or JCCB). The output contains the standard corr, corr_mu, smear_corr and smear_corrmu corrections.

It recomputes the corrections for:

• EM (currently not exactly what is done into d0correct)
• JES (only good and not EM jets are used)
• CH fraction of good and not EM jets (currently not exactly what is done into d0correct)
• muons

Required parameters:

• .From: Name of the branch the input MET
• .To: Name of output branch to store the new MET

Optional parameters:

• .Tree: OutputTreeName[default: name()]
• .jetBranch: Name of input jet branch (only the good and not EM jets of this branch will be used)
• .jetConeSize: jet cone size to be used (either 0.5 or 0.7). This has to be compatible with the jet algorithm used as input in jetBranch
• .useDefaultGoodJetDef: set if you want to recompute the CH fraction correction. if false: recompute the CH fraction correction with the good and not EM jet from the input jetBranch. if true (default): take the CH corrections from the input MET branch
• .muonBranch: Name of input good muon branch (it has to contain only good muons) if not specified (default): take the muon corrections from the input MET branch
• .electronBranch: Name of input electron branch if not specified (default): take the EM corrections from the input MET branch
• .JES: "NotShifted" use normal JES (default), "ShiftedPos" use JES shifted by +1 sigma, "ShiftedNeg" use JES shifted by -1 sigma.

If you only want to propagate the changes due to a new JES, you need only to specify: jetBranch and jetConeSize (the EM, CH and muon corrections can be copied from the input MET branch)

If you want to recompute the missing ET with a list of EM of jets where the good object definition is not the standard one, the EM-jet matching has to be done before calling for ReComputeMET.
