Here is the call graph for this function:

TMatrixT<double> EicPlanarRecoHit::getHMatrix ( const GFAbsTrackRep *  stateVector )

inlineprivatevirtual

Get transformation matrix. Transformation between hit coordinates and track representation coordinates.

This is a virtual abstract method which has to be implemented in the child classes.

In general there is a linear transformation between the coordinate system of the hit (which is defined by the detector plane) and the coordinates of the track representation in that plane. In the most simple case the track representation has 5 parameters (space + momentum) while a hit usually has less (one to three space coordinates).

The transformation matrix is then simply projecting out the space-components of the track representation.

Its dimensions are NxM. Where N is the number of dimensions of the hit in the detector plane (usually 2 or 1) and M is the dimension of the track representation.

In this method a hit has to define with which track representations it can work together. It should be the only point where this explicit coordination is necessary.

For example code see implementing classes below:

Implements GFAbsRecoHit.
