Cardinality (Maximum number of clones that can exist) special value 0 means that algorithm is reentrant.

Declare a new Gaudi property.

Recovery of missed hits.

Hits in the space point bucket that are maximally <RecoveryPull> away from the fitted segment are put onto the segment candidate and the candidate is refitted. If the refitted candidate has a chi2/nDoF < <OutlierRemoval> the canidate is automatically choosen otherwise, its chi needs to be better.

Parameters

ctx	EventContext needed for calibration of the hits
gctx	Geometry context needed if the beamspot constaint will be packed onto the segment
seed	Segment seed from the pattern recognition to access the underlying bucket
toRecover	Fit result with parameters & hits to recover.

We've the first estimator of the segment fit

Setup a map to replace space points if they better suite

Hit is already used in the segment fit

Remove the beamspot constraint measurement

Nothing has been recovered. Just bail out

If the chi2 is less than 5, no outlier rejection is launched. So also accept any recovered segment below that threshold

Next check whether the recovery made measurements marked as outlier feasable for the hole recovery

Finally remove all hits from the calib measurements which are obvious outliers

◆ removeOutliers()

bool MuonR4::SegmentFittingAlg::removeOutliers	(	const EventContext &	ctx,
		const ActsGeometryContext &	gctx,
		const SegmentSeed &	seed,
		SegmentFitResult &	fitResult
	)		const

private

Spot hits with large discrepancy from the estimated parameters and remove them from the list.

Parameters

ctx	EventContext needed for hit calibration
gctx	Geometry context needed if the beamspot constaint will be packed onto the segment
fitResult	Data structure carrying the fit parameters & calibrated hits

If no degree of freedom is in the segment fit then try to plug the holes

Remove a priori the beamspot constaint as it never should pose any problem and another one will be added anyway in the next iteration

Next sort the measurements by chi2

Declare the hit with the largest chi2 as outlier.

Remove the last measurement as it has the largest discrepancy
