struct GaussianSumFitter¶ - #include <Acts/TrackFitting/GaussianSumFitter.hpp>
Gaussian Sum Fitter implementation.
Note
This GSF implementation tries to be as compatible to the KalmanFitter as possible. However, strict compatibility is not garantueed.
Note
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.
- Template Parameters
propagator_t – The propagator type on which the algorithm is built on
bethe_heitler_approx_t – The type of the Bethe-Heitler-Approximation
traj_t – The MultiTrajectory type (backend)
Public Types
-
using GsfActor = detail::GsfActor<bethe_heitler_approx_t, traj_t>¶
The actor type.
The navigator type.
