Class Acts::MeasurementSelector¶
-
class 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
-
Result<std::pair<std::vector<MultiTrajectory::TrackStateProxy>::iterator, std::vector<MultiTrajectory::TrackStateProxy>::iterator>> select(std::vector<MultiTrajectory::TrackStateProxy> &candidates, bool &isOutlier, LoggerWrapper logger) const¶
Function that select the measurements compatible with the given track parameter on a surface.
- Parameters
candidates – The track state candidates which already contain predicted parameters
isOutlier – The indicator for outlier or not
logger – The logger wrapper
- Returns
Pair of iterators into candidates marking the range of selected candidates
