Detailed Description

Evaluate cluster kinematics with a different vertex / signal state.

This class acts as a proxy for a cluster object. It provides the same IParticle interface, except that the cluster kinematics are recalculated for a different vertex, and optionally a different signal state. When kinematics are recalculated w.r.t a vertex, the CENTER_MAG moment is used. This class is available in Athena and RootCore. See CaloVertexedCluster for a calculation based on the EM layer.

Constructor & Destructor Documentation

xAOD::CaloVertexedTopoCluster::CaloVertexedTopoCluster

(

const CaloCluster &

cl

)

Constructor.

Parameters:

cl

The cluster to proxy.

In this case, we'll return unchanged the kinematics of the cluster for the default signal state.

xAOD::CaloVertexedTopoCluster::CaloVertexedTopoCluster	(	const CaloCluster &	cl,
		CaloCluster::State	s
	)

Constructor.

Parameters:

	cl	The cluster to proxy.
	s	The desired signal state.

In this case, we'll return unchanged the kinematics of the cluster for signal state S.

xAOD::CaloVertexedTopoCluster::CaloVertexedTopoCluster	(	const CaloCluster &	cl,
		const Amg::Vector3D &	vx
	)

Constructor.

Parameters:

	cl	The cluster to proxy.
	vx	The vertex to use for calculating cluster kinematics.

In this case, we'll return unchanged the kinematics of the cluster relative to vertex vx for the default signal state.

xAOD::CaloVertexedTopoCluster::CaloVertexedTopoCluster	(	const CaloCluster &	cl,
		CaloCluster::State	s,
		const Amg::Vector3D &	vx
	)

Constructor.

Parameters:

	cl	The cluster to proxy.
	s	The desired signal state.
	vx	The vertex to use for calculating cluster kinematics.

In this case, we'll return unchanged the kinematics of the cluster relative to vertex vx for the default signal state. for signal state S.
