Constructor & Destructor Documentation

◆ OnTrackCalibrator() [1/2]

template<typename traj_t >

ActsTrk::detail::OnTrackCalibrator< traj_t >::OnTrackCalibrator ( )

default

Empty default constructor.

Surface look will fail.

◆ OnTrackCalibrator() [2/2]

template<typename traj_t >

ActsTrk::detail::OnTrackCalibrator< traj_t >::OnTrackCalibrator	(	const ActsTrk::ITrackingGeometryTool *	trackGeoTool,
		const ToolHandle< IOnTrackCalibratorTool< traj_t >> &	pixelTool,
		const ToolHandle< IOnTrackCalibratorTool< traj_t >> &	stripTool,
		const ToolHandle< IOnTrackCalibratorTool< traj_t >> &	hgtdTool
	)

Standard cosntructor which activates the calibration of the ITk & HGTD measurements based on the best track predicition.

It takes the configured instance to the TrackingGeometryTool and then for each silicon measurement type a calibration tool handle. There's also the possibility to pass an empty tool, then the information from the measurement is directly copied onto the track state. *

Parameters

trackGeoTool	Pointer to the tracking geometry tool to access the needed surfaces during the calibration
pixelTool	Reference to a (configured) calibration tool responsible for the PixelCluster measurements
stripTool	Reference to a (configured) calibration tool responsible for the ITk strip measurements
hdtdTool	Reference to a (configured) calibration tool responsible for the HGTD strip measurements

Member Function Documentation

◆ calibrate()

template<typename traj_t >

void ActsTrk::detail::OnTrackCalibrator< traj_t >::calibrate	(	const Acts::GeometryContext &	geoctx,
		const Acts::CalibrationContext &	cctx,
		const Acts::SourceLink &	link,
		TrackStateProxy	state
	)		const

Function that's hooked to the calibration delegate of the implemented Acts fitters.

Parameters

geoctx	The geometry context to fetch the local -> global transformations for the surfaces
cctx	Calibration context which is a packed pointer to the current ATLAS EventContext
link	Sourcelink to the actual measurement to calibrate
state	Proxy to the track state onto which the calibrated information is copied.

◆ NoCalibration()

template<typename traj_t >

static OnTrackCalibrator ActsTrk::detail::OnTrackCalibrator< traj_t >::NoCalibration ( const ActsTrk::ITrackingGeometryTool * trackGeoTool )

static

Constructs a calibrator which copies the local position & covariance of the ITk measurements onto the track state.

Parameters

trackGeoTool Pointer to a valid tracking geometry tool to associate the surfaces to the measurements
