Detailed Description

Class for measurements implementing a space point hit geometry.

For a space point the detector plane has to be defined with respect to a track representation. SpacepointMeasurement implements a scheme where the detectorplane is chosen perpendicular to the track. In a track fit, only two of the three coordinates of a space point are independent (the track is a one-dimensional object). Therefore the 3D data of the hit is used to define a proper detector plane into which the hit coordinates are then projected.

Member Function Documentation

virtual AbsMeasurement* genfit::SpacepointMeasurement::clone ( ) const

inlinevirtual

Deep copy ctor for polymorphic class.

Implements genfit::AbsMeasurement.

Reimplemented in genfit::ProlateSpacepointMeasurement.

Definition at line 55 of file SpacepointMeasurement.h.

References SpacepointMeasurement().

{return new SpacepointMeasurement(*this);}

virtual const AbsHMatrix* genfit::SpacepointMeasurement::constructHMatrix ( const AbsTrackRep *  ) const

virtual

Returns a new AbsHMatrix object. Caller must take ownership.

Implements genfit::AbsMeasurement.

virtual std::vector<MeasurementOnPlane*> genfit::SpacepointMeasurement::constructMeasurementsOnPlane ( const StateOnPlane &  state ) const

virtual

Construct MeasurementOnPlane on plane of the state and wrt the states TrackRep. The state will usually be the prediction or reference state, and has to be defined AT the measurement. The AbsMeasurement will be projected onto the plane. It's possible to make corrections to the coordinates here (e.g. by using the state coordinates). Usually the vector will contain only one element. But in the case of e.g. a WireMeasurement, it will be 2 (left and right).

Implements genfit::AbsMeasurement.

virtual SharedPlanePtr genfit::SpacepointMeasurement::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.
