Detailed Description

Tool interface to construct TrackSeeds from the MuonSegmentContainer.

The track seeds are processed by the calling algorithm to form MuonSpectrometer track candidates. The interface provides methods to

1) Construct a vector of track seed. The input how the track seed is constructed depends on the actual tool implementation of the interface

2) Estimate the start parameters for the track parameters for a given track seed. The technique in use may differ between the tool implementations

3) Extract an initial estimator of the track momentum given a set of 2 or 3 position-direction pairs + reference plane

estimateQtimesP()

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

pure virtual

Implemented in MuonR4::ITrackSeedingDiagnosticsTool.

estimateStartParameters()

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

pure virtual

findTrackSeeds()

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

pure virtual

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.
