A concrete implementation of the Vertex Updator using the Kalman filter algorithm.

This is a special implementation (part of the JetFitter algorithm) which is able to fit a vertex correcting the jet axis parameters to find the best overall agreement.

Basic approach is based on R. Fruhwirth et al. Comp. Phys. Comm 96(1996) 189

The first version implemented in TrkVertexFitterUtils, for general vertexing purposes, was created by Kirill Prokofiev and G.P.

First version: December 2006 Updated version for athena: Februar 2007

◆ add()

void Trk::KalmanVertexOnJetAxisUpdator::add ( VxTrackAtVertex *  trackToAdd,
const VxVertexOnJetAxis *  vertexToUpdate,
VxJetCandidate *  candidateToUpdate 
) const

Method updating the fit along the flight axis (VxJetCandidate) with a track (VxTrackOnJetAxis) which is added to the vertex along the jet axis provided (VxVertexOnJetAxis).

To update the fit with a new vertex (VxVertexOnJetAxis) you have to iteratively add all its tracks to the fit using this method. In the RecVertexPositions datamember of the VxJetCandidate the result will appear as the value of the distance of this fitted vertex from the primary vertex. All the other vertices and the jet direction will of course be also dynamically adjusted while adding tracks to the fit.

Method to create the Jacobian needed to go to the space of single vertices to the space of the variables representing the full fit along the flight axis (primary vertex, phi and theta of jet direction, distance to primary vertex of the remaining vertices along the jetaxis).

As a result the vector of position where the linearization was done and the jacobian are provided.

If the parameter truncate is true, the method also cuts the size of the matrix down to the only needed elements (if you work on vertex number 5, all the ones which come after are cut out from the jacobian to make the fit faster).

◆ remove()

void Trk::KalmanVertexOnJetAxisUpdator::remove ( VxTrackAtVertex *  trackToRemove,
const VxVertexOnJetAxis *  vertexToUpdate,
VxJetCandidate *  candidateToUpdate 
) const

Method removing already added track from the fit along the flight axis, where you specify from what vertex along the jet axis the track should be removed.

Usefull for smoothing and for estimating the compatibility of single vertices with the rest of the fit (the smoothed chi2 of the vertex can be obtained by iteratively removing all its tracks and storing the intermediate result at every time).

Just adding the chi2 of every track involved (as in Fruehwirth's reference) would lead here to misleading results.
