Detailed Description

Policy class implementing a poseudo space point hit geometry.

Author

Johannes Rauch (Technische Universität München, original author)

RecoHits for detectors measuring 3D space points with errors in one direction (the "wire direction") much larger than the errors perpendicular should inherit from RecoHitIfc<GFPseudoSpacepointWireHitPolicy>.

For these hits, a virtual detector plane lying in the POCA and perpendicular to the track yields wrong results. Instead, the plane should contain the direction of the largest error (i.e. the "wire direction").

The "wire direction" can be set. Standard is in z.

GFPseudoSpacepointWireHitPolicy::ClassDef	(	GFPseudoSpacepointWireHitPolicy	,
		1
	)

const GFDetPlane & GFPseudoSpacepointWireHitPolicy::detPlane	(	GFAbsRecoHit *	hit,
		GFAbsTrackRep *	rep
	)

Get detector plane perpendicular to track.

The detector plane is contructed from the position of the hit and the track representation. For this the track is extrapolated to the point of closest approach to a line parallel to z and containing the hit.
