Detailed Description

Interface of the Belle II B-field with GenFit.

Definition at line 16 of file GFGeant4Field.h.

Constructor & Destructor Documentation

GFGeant4Field()

GFGeant4Field ( )

inline

Constructor.

The same B field as in the simulation is used. If you want to use a different field in reconstruction, please run two jobs and change the used B field in the geometry data (Belle2.xml file).

Definition at line 24 of file GFGeant4Field.h.

: genfit::AbsBField() {}

Member Function Documentation

get() [1/2]

virtual void get ( const double &  posX, const double &  posY, const double &  posZ, double &  Bx, double &  By, double &  Bz  ) const

inlinevirtualinherited

Get the magneticField [kGauss] at position.

Override this in your concrete implementation.

Reimplemented in ConstField.

Definition at line 56 of file AbsBField.h.

{ const TVector3& B(this->get(TVector3(posX, posY, posZ))); Bx = B.X(); By = B.Y(); Bz = B.Z(); }

get() [2/2]

TVector3 get ( const TVector3 &  position ) const

inlineoverridevirtual

Getter for the magnetic field.

As Genfit uses kGauss, but we use T in basf2, we need to apply a factor 10 in the calculation.

Parameters

position

Position at which the magnetic field should be evaluated.

Implements AbsBField.
