Set the Geometry Context PLUGIN.
Set the Calibration Context PLUGIN.
Convenience functions to ease creation of and Acts::InterpolatedMaterialMap and to avoid code duplication.
Set the Mangetic Field Context PLUGIN.
Convenience functions to ease creation of and Acts::InterpolatedBFieldMap and to avoid code duplication.
Currently implemented for the two most common formats: rz and xyz.

class MeasurementSelector
- #include <Acts/TrackFinding/MeasurementSelector.hpp>
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 paremeters
isOutlier – The indicator for outlier or not
logger – The logger wrapper
- Returns
Pair of iterators into candidates marking the range of selected candidates

using Config = Acts::GeometryHierarchyMap<MeasurementSelectorCuts>
-
struct MeasurementSelectorCuts¶
- #include <Acts/TrackFinding/MeasurementSelector.hpp>
Selection cuts for associating measurements with predicted track parameters on a surface.
The default configuration only takes the best matching measurement without a cut on the local chi2.
