FactorizedJetCorrector

class coffea.jetmet_tools.FactorizedJetCorrector(**kwargs)

Bases: object

This class is a columnar implementation of the FactorizedJetCorrector tool in CMSSW and FWLite. It applies a series of JECs in ascending order as defined by ‘_level_order’, and checks for the consistency of input corrections.

It implements the jet energy correction definition specified in the JEC TWiki.

You can use this class as follows:

fjc = FactorizedJetCorrector(name1=corrL1,...)
jetCorrs = fjc(JetParameter1=jet.parameter1,...)

Attributes Summary

signature

list the necessary jet properties that must be input to this function

Methods Summary

getCorrection(**kwargs)	Returns the set of corrections for all input jets at the highest available level
getSubCorrections(**kwargs)	Returns the set of corrections for all input jets broken down by level

Methods Documentation

getCorrection(**kwargs)

Returns the set of corrections for all input jets at the highest available level

Use it like:

jecs = corrector.getCorrection(JetProperty1=jet.property1,...)

getSubCorrections(**kwargs)

Returns the set of corrections for all input jets broken down by level

Use it like:

jecs = corrector.getSubCorrections(JetProperty1=jet.property1,...)
#'jecs' will be formatted like [[jec_jet1 jec_jet2 ...] ...]
