Detailed Description

SVDRecoHit - an extended form of SVDHit containing geometry information.

To create a list of SVDRecoHits for all SVDTrueHits belonging to one MCParticle do something like:

//Get the MCParticle in question
MCParticle* mcParticle = ...
//Iterate over the relation and create a list of hits
vector<SVDRecoHit*> hits;
RelationIndex<MCParticle,SVDTrueHit> relMCTrueHit;
RelationIndex<MCParticle,SVDTrueHit>::range_from it = relMCTrueHit.getElementsFrom(mcParticle);
for(; it.first!=it.second; ++it.first){
  hits.push_back(new SVDRecoHit(it.first->to));
}

Constructor & Destructor Documentation

◆ SVDRecoHit() [1/2]

SVDRecoHit	(	const SVDTrueHit *	hit,
		bool	uDirection,
		float	sigma = `-1`
	)

Construct SVDRecoHit from a SVDTrueHit for Monte Carlo based tracking.

This requires a valid random number generator to be initialized at gRandom. The Hit position will be smeared using a gaussian smearing with sigma along u or v, depending on uDirection.

If the error is set to <0, the resolution will be set to pitch/sqrt(12).

Parameters

hit	SVDTrueHit to use as base
uDirection	If true, the hit has u coordinate, otherwise v
sigma	Error of the hit coordinate

Definition at line 31 of file SVDRecoHit.cc.

◆ SVDRecoHit() [2/2]

SVDRecoHit	(	const SVDCluster *	hit,
		const genfit::TrackCandHit *	trackCandHit = `nullptr`
	)

explicit

Construct SVDRecoHit from a SVD cluster.

Parameters

hit	SVDCluster to use as base.
trackCandHit	FIXME: Parameter sigma is no longer used and will be removed.

Definition at line 59 of file SVDRecoHit.cc.

Methods that actually interface to Genfit.

Definition at line 180 of file SVDRecoHit.cc.

◆ 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().
