Class Acts::Experimental::Gx2Fitter

template<typename propagator_t, typename traj_t>
class Gx2Fitter

Global Chi Square fitter (GX2F) implementation.

TODO Write description

Template Parameters

propagator_t – Type of the propagation class

Public Functions

inline auto fit(source_link_iterator_t it, source_link_iterator_t end, const start_parameters_t &sParameters, const Gx2FitterOptions<traj_t> &gx2fOptions, TrackContainer<track_container_t, traj_t, holder_t> &trackContainer) const -> std::enable_if_t<!_isdn, Result<typename TrackContainer<track_container_t, traj_t, holder_t>::TrackProxy>>

Fit implementation.

Note

The input measurements are given in the form of SourceLink s. It’s the calibrators job to turn them into calibrated measurements used in the fit.

Template Parameters

  • source_link_iterator_t – Iterator type used to pass source links

  • start_parameters_t – Type of the initial parameters

  • parameters_t – Type of parameters used for local parameters

  • track_container_t – Type of the track container backend

  • holder_t – Type defining track container backend ownership

Parameters

  • it – Begin iterator for the fittable uncalibrated measurements

  • end – End iterator for the fittable uncalibrated measurements

  • sParameters – The initial track parameters

  • gx2fOptions – Gx2FitterOptions steering the fit

  • trackContainer – Input track container storage to append into

Returns

the output as an output track
