Template Parameters

track_state_proxy_t

Type of the TrackStateProxy

Parameters

[in]	gctx	Geometry context
[in]	trackStateProxy	TrackStateProxy

Returns

Free parameters representation of the filtered parameters

freeSmoothed()

template<typename track_state_proxy_t>

FreeVector Acts::MultiTrajectoryHelpers::freeSmoothed	(	const GeometryContext &	gctx,

trajectoryState() [1/2]

template<typename traj_t>

TrajectoryState Acts::MultiTrajectoryHelpers::trajectoryState	(	const traj_t &	multiTraj,
		std::size_t	tipIndex )

Getter for global trajectory info.

Parameters

multiTraj	The MultiTrajectory object
tipIndex	The entry index of trajectory to investigate

Returns

Type of source link

Parameters

multiTraj	The MultiTrajectory object
tipIndex	The entry index of trajectory to investigate track states at different sub-detectors.
volumeIds	The container for sub-detector Ids

Returns

The trajectory summary info at different sub-detectors (i.e. different volumes)
