Detailed Description

The calibrated Space point is created during the calibration process.

It usually exploits the information of the external tracking seed. Calibrated space points may also be created without a link to a measurement space point. In this case, they serve in an analogous way as the Trk::PseudoMeasurement

Member Enumeration Documentation

◆ State

enum MuonR4::CalibratedSpacePoint::State : uint8_t

strong

State flag to distinguish different space point states.

Valid: Calibration of the space point was successful and it should be used in the fit
FailedCalib: The calibration procedure produced invalid constants and the space point shall not be included in the current chi2 iteration, but may tried in the next cycle
Outlier: The Space point is an outlier and shall never be included in the fit. It's kept for the hit counting purpose but nothing else
