Detailed Description

Class for measurements implementing a space point hit geometry with a very prolate form of the covariance matrix.

Author
Johannes Rauch (Technische Universität München, original author)

Measurements from detectors measuring 3D space points with errors in one direction much larger than the errors perpendicular should use this class.

For these hits, a virtual detector plane lying in the POCA and perpendicular to the track yields wrong results. Instead, the plane should contain the direction of the largest error.

The largest error direction can be set. Standard is in z.

SharedPlanePtr genfit::ProlateSpacepointMeasurement::constructPlane ( const StateOnPlane state) const
virtual

Contruct the virtual detector plane.

Per default, the plane will be constructed such that it contains the measurement and POCA to the measurement in cartesian space. The plane is perpendicular to the track (at the POCA).

If weightedPlaneContruction_ is set, the POCA will be calculated in a space weighted with the inverse of the 3D covariance. E.g. if the covariance is very oblate, the plane will be almost defined by the covariance shape. If the covariance is very prolate, the behaviour will be very similar to the ProlateSpacepointHit.
