Detailed Description

Contains the measurement and covariance in raw detector coordinates.

Detector and hit ids can be used to point back to the original detector hits (clusters etc.).

Member Function Documentation

constructHMatrix()

virtual const AbsHMatrix* constructHMatrix ( const AbsTrackRep *  ) const

pure virtual

Returns a new AbsHMatrix object.

Caller must take ownership.

Implemented in PlanarMomentumMeasurement, SVDRecoHit, PXDRecoHit, CDCRecoHit, AlignableBKLMRecoHit, WirePointMeasurement, WireMeasurementNew, WireMeasurement, SpacepointMeasurement, PlanarMeasurement, and FullMeasurement.

constructMeasurementsOnPlane()

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

pure 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).

Implemented in WirePointMeasurement, WireMeasurementNew, WireMeasurement, SpacepointMeasurement, PlanarMeasurement, FullMeasurement, PlanarVXDMomentumMeasurement< HitType >, SVDRecoHit2D, SVDRecoHit, PXDRecoHit, CDCRecoHit, and AlignableBKLMRecoHit.

constructPlane()

virtual SharedPlanePtr constructPlane ( const StateOnPlane &  state ) const

pure virtual

Construct (virtual) detector plane (use state's AbsTrackRep).

It's possible to make corrections to the plane here. The state should be defined somewhere near the measurement. For virtual planes, the state will be extrapolated to the POCA to point (SpacepointMeasurement) or line (WireMeasurement), and from this info the plane will be constructed.

Implemented in WirePointMeasurement, WireMeasurementNew, WireMeasurement, SpacepointMeasurement, PlanarMeasurement, FullMeasurement, ProlateSpacepointMeasurement, and CDCRecoHit.
