Detailed Description

Track Representation module based on a Runge-Kutta algorithm including a full material model.

Author: Christian Höppner (Technische Universität München, original author); Johannes Rauch (Technische Universität München, author)

The Runge Kutta implementation stems from GEANT3 originally (R. Brun et al.). Porting to C goes back to Igor Gavrilenko @ CERN. The code was taken from the Phast analysis package of the COMPASS experiment (Sergei Gerrassimov @ CERN).

The covariance matrix is transformed from the plane coordinate system to the master reference system (for the propagation) and, after propagation, back to the plane coordinate system.
Also the parameter spu (which is +1 or -1 and indicates the direction of the particle) is calculated and stored in #fCacheSpu. The plane is stored in #fCachePlane.
Master reference system (MARS):

\begin{eqnarray*}x & = & O_{x}+uU_{x}+vV_{x}\\y & = & O_{y}+uU_{y}+vV_{y}\\z & = & O_{z}+uU_{z}+vV_{z}\\a_{x} & = & \frac{\mbox{spu}}{\widetilde{p}}\left(N_{x}+u\prime U_{x}+v\prime V_{x}\right)\\a_{y} & = & \frac{\mbox{spu}}{\widetilde{p}}\left(N_{y}+u\prime U_{y}+v\prime V_{y}\right)\\a_{z} & = & \frac{\mbox{spu}}{\widetilde{p}}\left(N_{z}+u\prime U_{z}+v\prime V_{z}\right)\\\frac{q}{p} & = & \frac{q}{p}\end{eqnarray*}

Plane coordinate system:

\begin{eqnarray*}u & = & \left(x-O_{x}\right)U_{x}+\left(y-O_{y}\right)U_{y}+\left(z-O_{z}\right)U_{z}\\v & = & \left(x-O_{x}\right)U_{x}+\left(y-O_{y}\right)U_{y}+\left(z-O_{z}\right)U_{z}\\u\prime & = & \frac{a_{x}U_{x}+a_{y}U_{y}+a_{z}U_{z}}{a_{x}N_{x}+a_{y}N_{y}+a_{z}N_{z}}\\v\prime & = & \frac{a_{x}V_{x}+a_{y}V_{y}+a_{z}V_{z}}{a_{x}N_{x}+a_{y}N_{y}+a_{z}N_{z}}\\\frac{q}{p} & = & \frac{q}{p}\\\mbox{spu} & = & \frac{a_{x}N_{x}+a_{y}N_{y}+a_{z}N_{z}}{|a_{x}^{2}N_{x}^{2}+a_{y}^{2}N_{y}^{2}+a_{z}^{2}N_{z}^{2}|}=\pm1\end{eqnarray*}

Get auxillary information from the track representation.

AuxInfo is a mechanism which allows creators of track repersentations to hand out any information they like (as long as it is compatible with a TMatrixT<double>). It should be used if setData requires additional information to update the representation, but it can also be used for debugging information if needed. See also the documentation of GFAbsTrackRep::setData().

	)

virtual

Sets state, plane and (optionally) covariance.

This function also sets the parameter #fSpu to the value stored in #fCacheSpu. Therefore it has to be ensured that the plane #pl is the same as the plane of the last extrapolation (i.e. #fCachePlane), where #fCacheSpu was calculated. Hence, if the argument #pl is not equal to #fCachePlane, an error message is shown an an exception is thrown.
