AlgebraicSymMatrix55 | theCovarianceMatrix |
This frame is tangent to the track at the point of definition, with Z_T parallel to the track. X_T is in the global xy plane and points to the left when looking into the direction of the track, and Y_T forms a right-handed frame with X_T and Z_T.
The error along Z_T is therefore zero. The parameters are
sigma^2( charge / abs_momentum)
sigma^2( lambda)
sigma^2( phi)
sigma^2( x_transverse))
sigma^2( y_transverse))
Please note that lambda and phi are defined in the global frame. Lambda is the helix dip angle (pi/2 minus theta (polar angle)), while phi is the angle of inclination with the global x-axis in the transverse (global xy) plane.
