Result container for a global chi-square fit.

Member Data Documentation

lastMeasurementIndex

template<typename traj_t>

std::size_t Acts::Experimental::Gx2FitterResult< traj_t >::lastMeasurementIndex = Acts::kTrackIndexInvalid

This is the index of the 'tip' of the track stored in multitrajectory.

This corresponds to the last measurement state in the multitrajectory. Since this KF only stores one trajectory, it is unambiguous. Acts::TrackTraits::kInvalid is the start of a trajectory.

lastTrackIndex

template<typename traj_t>

std::size_t Acts::Experimental::Gx2FitterResult< traj_t >::lastTrackIndex = Acts::kTrackIndexInvalid

This is the index of the 'tip' of the states stored in multitrajectory.

This corresponds to the last state in the multitrajectory. Since this KF only stores one trajectory, it is unambiguous. Acts::TrackTraits::kInvalid is the start of a trajectory.

measurementHoles

template<typename traj_t>

std::size_t Acts::Experimental::Gx2FitterResult< traj_t >::measurementHoles = 0

Counter for measurements holes A hole correspond to a surface with an associated detector element with no associated measurement.

Holes are only taken into account if they are between the first and last measurements.
