MeasurementType

enum Trk::TrackState::MeasurementType

enum describing the flavour of MeasurementBase

This enum is for use in interfaces, track fitting logic and caching of idHelper calls (like is_pixel). Note that it is not an official part of the MeasurementBase EDM, therefore the decisive identification remains with the Tracking EDM inheritance structure and the hit identifiers.

Enumerator
AnyState	fittable or outlier
Fittable	normal MeasurementBase
ExternalOutlier	input outlier from pattern or previous fit
GeneralOutlier	outlier for unspecified reason
StateOutlier	standard cut on pull or smoothed state Chi2
AssProbOutlier	cut on hit assignment probability (also state)
TrackOutlier	selected outlier to enhance track probability
PredictedOutlier	determined from fit result without this state
SensorOutlier	track prediction is signif'ly outside sensor
FilterOutlier	progressive fit: removed to stabilise fit
MissedOutlier	progressive fit: missed by extrapolation
DuplicateOutlier	same hit is already on track, should not happen!
Hole	a hole on track, or a generic surface on track
Scatterer	a scatterer, i.e. a surface where the track direction changes
Brem	a brem, i.e. a surface where the momentum changes
