Detailed Description

The TrajectoryMeasurement contains the full information about the measurement of a trajectory by a Det, namely

• the TrackingRecHit
  
• the predicted TrajectoryStateOnSurface from forward propagation (fitter)
  
• the predicted TrajectoryStateOnSurface from backward propagation (smoother)
  
• the (combination of the) predicted TrajectoryStateOnSurfaces updated with the TrackingRecHit information
  
• the compatibility estimate between the TrackingRecHit and the predicted state.
  

A container of TrajectoryMeasurements is the result of querying a Det for measurements compatible with a TrajectoryState. A reconstructed track also consists of an ordered collection of TrajectoryMeasurements.
