Detailed Description

creates SCT_ClusterOnTrack objects allowing to calibrate cluster position and error using a given track hypothesis.

See doxygen of Trk::RIO_OnTrackCreator for details. Different strategies to calibrate the cluster error can be chosen by job Option. Also the handle to the general hit-error scaling is implemented.

produces an SCT_ClusterOnTrack using the measured SCT_Cluster and the track prediction.

This method is a factory, so the client has to take care of management/deletion of the SCT_ClusterOnTrack.

Implements Trk::IRIO_OnTrackCreator.

protectedinherited

Add StoreName to extra input/output deps as needed.

use the logic of the VarHandleKey to parse the DataObjID keys supplied via the ExtraInputs and ExtraOuputs Properties to add the StoreName if it's not explicitly given

◆ finalize()

AlgTool termination.

◆ getCorrection()

double InDet::SCT_ClusterOnTrackTool::getCorrection	(	double	phi,

static

Returns a correction to be applied to the SCT cluster local x position in simulated events to remove a position bias introduced by the SCT digitisation.

Parameters

[in]	phi	angle of track relative to Lorentz drift direction, in transverse plane
[in]	nstrip	SCT cluster size (number of strips)

◆ getError()

double InDet::SCT_ClusterOnTrackTool::getError	(	double	phi,
		int	nstrip
	)

static

Returns the resolution on the reconstructed position (local x) of SCT clusters in simulated events.

Parameters

[in]	phi	angle of track relative to Lorentz drift direction, in transverse plane
[in]	nstrip	SCT cluster size (number of strips)

The parameterisation of the resolution contained in getError() was derived from SCT barrel clusters (80 micron pitch). It can be applied also to endcap clusters, after rescaling to the appropriate pitch.
