Detailed Description

template<class HitType, Const::EDetector detector>
class Belle2::VXDMomentumEstimationMeasurementCreator< HitType, detector >

Creator for VXDMeasurements with momentum estimation based on the dEdX information.

Can use different possibilities to calculate the path length needed for the dEdX calculation. Needs the transformation fit parameters fitParameters and correctionFitParameters which can be calculated using the IPython notebook Analyse_Hitwise.ipynb.

protectedinherited

You probably need a coordinate measurement on which you can base your measurements in createMeasurements.

This function uses the measurementFactory to create one. Please be aware that this creates two new objects on the heap: the measurement and the track point. If you do not plan to use those two in a track, please delete them! The track point can be deleted by accessing the measurements GetTrackPoints function.

Parameters

hit
recoHitInformation

Returns: a coordinate AbsMeasurement as pointer.

◆ m_correctionFitParameters

Parameters for the correction function.

Set them to zero to not use a correction function.
