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

◆ SVDRecoHit2D() [1/4]

SVDRecoHit2D	(	const SVDTrueHit *	hit,
		const genfit::TrackCandHit *	trackCandHit = `nullptr`,
		float	sigmaU = `-1`,
		float	sigmaV = `-1`
	)

explicit

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 sigmaU and sigmaV along u and v respectively

If one of the errors is set <0, a default resolution will be assumed for both values by dividing the pixel size by sqrt(12).

Parameters

hit	SVDTrueHit to use as base
trackCandHit
sigmaU	Error of the Hit along u
sigmaV	Error of the Hit along v

Definition at line 29 of file SVDRecoHit2D.cc.

◆ SVDRecoHit2D() [2/4]

SVDRecoHit2D	(	VxdID::baseType	vxdid,
		const double	u,
		const double	v,
		double	sigmaU = `-1`,
		double	sigmaV = `-1`
	)

Construct SVDRecoHit directly from vxdid and coordinates without using a hit object from the storearray in the constructor.

Parameters

vxdid	the vxd id so the reco hit knows on which sensor the measurment took place
u	coordinate of the Hit along u
v	coordinate of the Hit along v
sigmaU	Error of the Hit along u
sigmaV	Error of the Hit along v

Definition at line 59 of file SVDRecoHit2D.cc.

◆ SVDRecoHit2D() [3/4]

SVDRecoHit2D	(	const SVDCluster &	uHit,
		const SVDCluster &	vHit
	)

Construct SVDRecoHit from a u- and v- SVDCluster.

Parameters

uHit	the u-type SVDCluster
vHit	the v-type SVDCluster

Definition at line 81 of file SVDRecoHit2D.cc.

◆ SVDRecoHit2D() [4/4]

SVDRecoHit2D	(	const SVDRecoHit &	uRecoHit,
		const SVDRecoHit &	vRecoHit
	)

Construct SVDRecoHit from a u- and v- (1D) SVDRecoHit.

Parameters

uRecoHit	the u-type SVDRecoHit
vRecoHit	the v-type SVDRecoHit

Definition at line 118 of file SVDRecoHit2D.cc.

Member Function Documentation

◆ clone()

genfit::AbsMeasurement * clone ( ) const

overridevirtual

Creating a deep copy of this hit.

Overrides the method inherited from GFRecoHit.

Reimplemented from PlanarMeasurement.

Definition at line 226 of file SVDRecoHit2D.cc.

◆ constructHMatrix()

const AbsHMatrix * constructHMatrix ( const AbsTrackRep * ) const

overridevirtualinherited

Returns a new AbsHMatrix object.

Caller must take ownership.

Implements AbsMeasurement.

Reimplemented in PlanarMomentumMeasurement, SVDRecoHit, PXDRecoHit, and AlignableBKLMRecoHit.

Definition at line 67 of file PlanarMeasurement.cc.

◆ constructMeasurementsOnPlane()

std::vector< genfit::MeasurementOnPlane * > constructMeasurementsOnPlane ( const genfit::StateOnPlane & state ) const

overridevirtual

Get deposited energy error.

Methods that actually interface to Genfit.

Reimplemented from PlanarMeasurement.

Definition at line 217 of file SVDRecoHit2D.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().
