Detailed Description

Measurement class implementing a planar hit geometry (1 or 2D).

Author

Sebastian Neubert (Technische Universität München, original author)
Johannes Rauch (Technische Universität München, original author)

The main feature of this type of hit is, that the detector plane is defined by the detector hardware.

+ Here is the caller graph for this function:

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

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).

SharedPlanePtr genfit::PlanarMeasurement::constructPlane ( const StateOnPlane &  state) const
overridevirtual

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.

Use if the coordinate for 1D hits measured in V direction.

Per default for 1D planar hits, the coordinate is measured in U direction. With this function you can set it to be measured in V direction. This affects the outcoe of constructHMatrix().
