Member Function Documentation

getWireBackwardPosition() [1/2]

virtual const B2Vector3D getWireBackwardPosition ( const WireID &  wireID )

pure virtual

Beginning of wire in the more backward position.

Implemented in IdealCDCGeometryTranslator, and RealisticCDCGeometryTranslator.

getWireBackwardPosition() [2/2]

virtual const B2Vector3D getWireBackwardPosition ( const WireID &  wireID, float  z  )

pure virtual

Beginning of imaginary wire in the more backward position.

Implemented in RealisticCDCGeometryTranslator, and IdealCDCGeometryTranslator.

getWireForwardPosition() [1/2]

virtual const B2Vector3D getWireForwardPosition ( const WireID &  wireID )

pure virtual

End of wire in the more forward position.

Implemented in IdealCDCGeometryTranslator, and RealisticCDCGeometryTranslator.

getWireForwardPosition() [2/2]

virtual const B2Vector3D getWireForwardPosition ( const WireID &  wireID, float  z  )

pure virtual

End of imaginary wire in the more forward position.

The GFWireHitPolicy needs the endpoints of the wires and assumes a straight line between those endpoints. Around these lines circular drift-isochrones are assumed. During the tracking the z-position of the actual hit is known quite well, which means, that individual corrections due to wire sag, etc. can be applied by moving the endpoints accordingly.

Implemented in RealisticCDCGeometryTranslator, and IdealCDCGeometryTranslator.
