Class Acts::MeasurementSelector¶
-
class Acts::MeasurementSelector¶
Measurement selection struct selecting those measurements compatible with the given track parameter against provided criteria on one surface.
The selection criteria could be allowed maximum chi2 and allowed maximum number of measurements on one surface
If there is no compatible measurement, the measurement with the mininum chi2 will be selected and the status will be tagged as an outlier
Public Types
-
using Config = Acts::GeometryHierarchyMap<MeasurementSelectorCuts>¶
Geometry-dependent cut configuration.
Different components on the geometry can require different cut settings. The configuration must either contain explicit settings for all geometry components that are used or contain a global default.
Public Functions
-
MeasurementSelector() = default¶
Default constructor.
-
inline MeasurementSelector(Config config)¶
Constructor with config and (non-owning) logger.
- Parameters
config – a config instance
-
template<typename measurement_t>
inline Result<void> operator()(const BoundTrackParameters &predictedParams, const std::vector<measurement_t> &measurements, std::vector<std::pair<size_t, double>> &measChi2, std::vector<size_t> &measCandidateIndices, bool &isOutlier, LoggerWrapper logger) const¶ Operater that select the measurements compatible with the given track parameter on a surface.
- Template Parameters
measurement_t – The type of measurement
- Parameters
predictedParams – The predicted track parameter on a surface
measurements – The pool of measurements
measChi2 – The container for index and chi2 of intermediate measurement candidates
measCandidateIndices – The container for index of final measurement candidates
isOutlier – The indicator for outlier or not
logger – The logger wrapper
