| AlgebraicSymMatrix66 | theCovarianceMatrix |
This error matrix should be used with care and in particular not as an intermediate frame when transforming between different, 5-dimensional track parameter frames. The order of the quantities inside the error matrix is the same as for the corresponding parameter vector provided by the GlobalTrajectoryParameters class.
