Detailed Description

Store reconstructed trajectories from track finding/fitting.

It contains a MultiTrajectory with a vector of entry indices for individual trajectories, and a map of fitted parameters indexed by the entry index. In case of track fitting, there is at most one trajectory in the MultiTrajectory; In case of track finding, there could be multiple trajectories in the MultiTrajectory.

Member Typedef Documentation

IndexedParameters

using Jug::Trajectories::IndexedParameters = std::unordered_map<size_t, TrackParameters>

Fitted parameters identified by indices in the multi trajectory.

MultiTrajectory

using Jug::Trajectories::MultiTrajectory = ::Acts::MultiTrajectory

(Reconstructed) trajectory with multiple states.

Constructor & Destructor Documentation

Trajectories() [1/2]

Jug::Trajectories::Trajectories ( )

default

Default construct an empty object. Required for container compatibility and to signal an error.

Trajectories() [2/2]

Jug::Trajectories::Trajectories ( const MultiTrajectory &  multiTraj, const std::vector< size_t > &  tTips, const IndexedParameters &  parameters  )

inline

Construct from fitted multi trajectory and parameters.

Parameters

multiTraj	The multi trajectory
tTips	Tip indices that identify valid trajectories
parameters	Fitted track parameters indexed by trajectory index
