Member Function Documentation

DeclareInterfaceID() [1/2]

MuonR4::ITrackSeedingDiagnosticsTool::DeclareInterfaceID	(	MuonR4::ITrackSeedingDiagnosticsTool	,
		1	,
		0	)

Declare the interface.

DeclareInterfaceID() [2/2]

MuonR4::ITrackSeedingTool::DeclareInterfaceID ( MuonR4::ITrackSeedingTool , 1 , 0  )

inherited

Declare the interface.

estimateQtimesP() [1/2]

virtual double MuonR4::ITrackSeedingDiagnosticsTool::estimateQtimesP ( const Acts::GeometryContext & tgContext, const MsTrackSeed & seed, MagField::AtlasFieldCache & fieldCache ) const

pure virtual

Estimate the charge times momentum of a muon track candidate from the contained segments.

The position and direction of the segments are projected onto a given phi plane, defined by the segments with phi information or the sector plane.
The muon trajectory is approximated as 2D trajectory within this plane to avoid side effects from (non)-present phi measurements.

Parameters

tgContext	The geometry context to align the segment w.r.t sector
seed	Reference to the seed of interest.
fieldCache	The initialized magnetic field map

estimateQtimesP() [2/2]

virtual double MuonR4::ITrackSeedingTool::estimateQtimesP ( const EventContext & ctx, const Amg::Vector3D & planeNorm, std::span< const PosMomPair_t > circlePoints ) const

virtual

Take the interface estimateQtimesP method upstream.

Implements MuonR4::ITrackSeedingTool.

estimateStartParameters()

virtual Acts::Result< Acts::BoundTrackParameters > MuonR4::ITrackSeedingTool::estimateStartParameters ( const EventContext & ctx, const MsTrackSeed & seed ) const

pure virtualinherited

expressOnCylinder()

virtual Amg::Vector2D MuonR4::ITrackSeedingDiagnosticsTool::expressOnCylinder ( const Acts::GeometryContext & tgContext, const xAOD::MuonSegment & segment, const Location loc, const ExpandedSector sector ) const

pure virtual

Expresses the passed segment on the virtual cylinder constructed by the track seeder.

The segment's position is projected onto the expanded sector plane using the sensor dircection of the first precision measurement. Then projected position and the direction vector are projected into 2D to intersect with the cylinder surface.

Parameters

tgContext	The geometry context to align the measurement surfaces associated with the segment
segment	The segment that is to be projected.
loc	Location of the projection [barrel/endcap]
sector	Phi sector onto which the segment is moved

findTrackSeeds()

virtual StatusCode MuonR4::ITrackSeedingTool::findTrackSeeds ( const EventContext & ctx, std::vector< MsTrackSeed > & outSeeds ) const

pure virtualinherited

Retrieves the segment container from StoreGate and constructs TrackSeeds from them.

The seed canddiates are pushed to the output seed container

Parameters

ctx	EventContext to access the xAOD::MuonSegmentContainer from store gate and additional conditions data if needed to construct the seed
outSeeds	Mutable reference to the container to whichh the seeds are pushed to.

withinBounds()

virtual bool MuonR4::ITrackSeedingDiagnosticsTool::withinBounds ( const Amg::Vector2D & projPos, const Location loc ) const

pure virtual

Returns whether the expression on the cylinder is within the surface bounds.

Parameters

projPos	Projected position on the cylinder
loc	Surface location: [barrel/endcap]
