Detailed Description

template<typename propagator_t, typename bethe_heitler_approx_t, typename traj_t>
struct Acts::GaussianSumFitter< propagator_t, bethe_heitler_approx_t, traj_t >

Gaussian Sum Fitter implementation.

Template Parameters
propagator_tThe propagator type on which the algorithm is built on
bethe_heitler_approx_tThe type of the Bethe-Heitler-Approximation
traj_tThe MultiTrajectory type (backend)
Note
This GSF implementation tries to be as compatible to the KalmanFitter as possible. However, strict compatibility is not garantueed.
Currently there is no possibility to export the states of the individual components from the GSF, the only information returned in the MultiTrajectory are the means of the states. Therefore, also NO dedicated component smoothing is performed as described e.g. by R. Fruewirth.
