The MeasurementBase class

Introduction

This package includes the pure absract base class Trk::MeasurementBase for all fittable measurements in the Tracking realm. It holds the minimal common interface which is characterized by

• Trk::LocalParameters*
• Trk::ErrorMatrix*
• Trk::Surface*
• Trk::GlobalPosition*

The following child branches are (planned) to inherit from this one (only base classes are given here):

• Trk::RIO_OnTrack, calibrated measurement on track
• Trk::Segment, track segment class with calibrated measurements on track
• Trk::CompetingRIO_OnTrack, data structure for DAF with multiple competing RIO_OnTracks
• Trk::SpacePoint, 3D space points to allow fitting on HLT level (planned)

Please let me know of any errors, or if anything is unclear.
