Detailed Description

template<class HitType>
class Belle2::PlanarVXDMomentumMeasurement< HitType >

Measurement class implementing a planar hit geometry (1 or 2D) with a momentum measurement based on the VXD dEdX information with setable parameters (see VXDMomentumEstimationMeasurementCreator).

Constructor & Destructor Documentation

◆ PlanarVXDMomentumMeasurement()

PlanarVXDMomentumMeasurement ( const genfit::PlanarMeasurement parentElement,
HitType *  hit,
const Belle2::RecoTrack recoTrack 
)
inline

Initialize the momentum measurement with a planar measurement as a parent, the corresponding hit and the reco track to get information from.

The internal matrices are set accordingly.

Definition at line 34 of file PlanarVXDMomentumMeasurement.h.

Member Function Documentation

◆ constructPlane()

SharedPlanePtr constructPlane ( const StateOnPlane state) const
overridevirtualinherited

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.

Implements AbsMeasurement.

Definition at line 46 of file PlanarMeasurement.cc.

◆ setStripV()

void setStripV ( bool  v = true)
inlineinherited

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().

Definition at line 70 of file PlanarMeasurement.h.

Member Data Documentation

◆ m_correctionFitParameters

VXDMomentumEstimation<HitType>::CorrectionFitParameters m_correctionFitParameters
private

Parameters for the correction function.

Set them to zero to not use a correction function.
