Detailed Description

Danilo's approximation of mini-isolation which has been calculated in AnalysisTop and applied as a decoration to the objects.

This gave you something to work with before the DC14 derivations included isolation (which they should by the time you read this). Probably other options will be better, and almost certainly faster if we don't need to load all the tracks!

Constructor & Destructor Documentation

ApproxPTVarCone()

top::ApproxPTVarCone::ApproxPTVarCone	(	double	fraction,
		double	fractionLoose
	)

An approximation of mini-isolation.

This applies some sort of fractional cut to mini-iso / particle pT.

Parameters

fraction	For the tight (analysis) leptons
fractionLoose	For leptons that will be used in the background estimate.

Definition at line 91 of file IsolationTools.cxx.

Member Function Documentation

passSelection()

bool top::ApproxPTVarCone::passSelection ( const xAOD::IParticle &  p ) const
