Detailed Description

Evaluate cluster kinematics with a different vertex / signal state.

A base for classes acting as a proxy for a cluster object. Concrete classes are

CaloVertexedCluster : vertex correction uses the EM layer information. Available only in athena, since geometry is required.
CaloVertexedTopoCluster : vertex correction uses the "" It provides the same IParticle interface, except that the cluster kinematics are recalculated for a different vertex, and optionally a different signal state.

xAOD::CaloVertexedClusterBase::CaloVertexedClusterBase ( 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::CaloVertexedClusterBase::CaloVertexedClusterBase	(	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.

void xAOD::CaloVertexedClusterBase::computeVertexCorr	(	const Amg::Vector3D &	vx,
		double	radius
	)			`[protected]`

Calculate cluster kinematics for a given vertex.

Parameters:

vx

The vertex to use for calculating cluster kinematics.
