doFitAndCut()

std::tuple< bool, int, std::unique_ptr< Trk::Track > > InDet::SiSPGNNTrackMaker::doFitAndCut ( const EventContext & ctx, std::vector< const Trk::SpacePoint * > & spacePoints, std::vector< const Trk::PrepRawData * > & clusters, int & trackCounter ) const

protected

Fits a track and applies quality cuts to determine if it should be kept.

Parameters

ctx	Event context for conditions access
clusters	Vector of cluster measurements used to fit the track
initial_params	Initial track parameters from seed finding
trackCounter	Index/ID of the track candidate being processed

Returns

std::tuple<bool, int, std::unique_ptr<Trk::Track>>

• bool: Whether the fit was successful
• int: Error/status code (0 for success, >0 for specific failure modes)
• Track: The fitted track (nullptr if fit fails or track rejected)

This function performs the following steps:

1. Fits the track using the provided clusters and initial parameters
2. Checks basic kinematic cuts (pT, eta)
3. Computes track summary (hits, holes)
4. Applies eta-dependent quality cuts if configured

Error codes:

• 0: Success, track passes all cuts
• 1: Failed minimum silicon hits requirement
• 2: Failed minimum pixel hits requirement
• 3: Failed minimum pT requirement
• 4: Failed maximum z0 requirement
• 5: Failed maximum d0 requirement
• 6: Failed maximum holes requirement
• 999: Track fit failed

Note

The track fitting is performed using the configured track fitter tool

Quality cuts are configurable via job options
