Package providing Jet uncertainties/corrections:
 * obtain JES uncertainty ([[https://twiki.cern.ch/twiki/bin/view/AtlasProtected/MultijetJESUncertaintyProviderTop|official documentation]])

{{{
svn co svn+ssh://svn.cern.ch/reps/desyatfw/CommonAnalysis/Common/JetCPTools/trunk JetCPTools
}}}

=== recommended tags ===

until tested version exists use trunk

== known problems ==

none.

These warnings from the JESUncertaintyTool are OK and known:
{{{
 (WARNING)  TNamed::Multije... : analysis sample response larger than light quark jet response: setting response(sample)/r_incl = response(light quarks)/r_incl --> Check input graph responseSample in file $SFRAME_DIR/../Common/JetCPTools/files/MJESttbarSemi_rel16.root!
}}}

== example code ==

{{{
for( JetVecIt it_jets = AllJets.begin(); it_jets != AllJets.end(); ++it_jets ) {
    double uncertainty = m_jesUncertaintyTool.getUncertainty(*it_jets, AllJets, collisionVertexN, 1.);
    // don't forget to correct MET!
}
}}}
