Hist

Description

Contains the histograms that are filled in getMultiJetobservables. These histograms are filled through the different Fill() methods.

The attributes of this structure are the following:

• name --> name of the instance to avoid memory leak
• njets --> histogram of the number of jets in the event
• dsigmadphi --> $\Delta \phi$ between the leading and subleading Jets
• ptleading --> $p_T$ of the leading jet (in term of pt)
• deta --> Delta Eta distribution between the leading and subleading Jets
• pt --> pt of all the jets in the event
• pteta --> 2D histogram binned in $p_T$ and $\Delta\eta$
• Ht --> $H_T$ of the event
• EF --> Energy fraction of the leading jet
• SpT --> $S_{p_T} $ of the event see MultiJets::SpT()
• Sphi --> $S_{\phi}$ of the event see MultiJets::Sphi()
