Constructor & Destructor Documentation

Gx2FitterExtensions()

template<typename traj_t>

MuonExperimental::Gx2FitterExtensions< traj_t >::Gx2FitterExtensions ( )

inline

Default constructor which connects the default void components.

Definition at line 277 of file Chi2Fitter.h.

                        {
    calibrator.template connect<&Acts::detail::voidFitterCalibrator<traj_t>>();
    outlierFinder.template connect<&Acts::detail::voidOutlierFinder<traj_t>>();
    surfaceAccessor.connect<&Acts::detail::voidSurfaceAccessor>();
    elossAccumulator
        .connect<&Gx2fMaterialProperties::ELossAtSurface::invalidELoss>();
  }

Member Data Documentation

calibrator

template<typename traj_t>

Calibrator MuonExperimental::Gx2FitterExtensions< traj_t >::calibrator

The Calibrator is a dedicated calibration algorithm that allows to calibrate measurements using track information, this could be e.g.

sagging for wires, module deformations, etc.

Definition at line 267 of file Chi2Fitter.h.

elossAccumulator

template<typename traj_t>

ELossAccumulator MuonExperimental::Gx2FitterExtensions< traj_t >::elossAccumulator

The elossAcumulator is the hook to use the measured energy loss instead of the estimated energy loss from the tracking geometry.

The accumulator is called at every material surface. If the accumulator returns a valid ELossAtSurface object i.e. the lost energy and the associated uncertainty need to be greater than zero, this value is taken instead of the parameterized energy loss from the Highland formula

Definition at line 263 of file Chi2Fitter.h.

outlierFinder

template<typename traj_t>

OutlierFinder MuonExperimental::Gx2FitterExtensions< traj_t >::outlierFinder

Determines whether a measurement is supposed to be considered as an outlier.

Definition at line 271 of file Chi2Fitter.h.

surfaceAccessor

template<typename traj_t>

SourceLinkSurfaceAccessor MuonExperimental::Gx2FitterExtensions< traj_t >::surfaceAccessor

Retrieves the associated surface from a source link.
