Detailed Description

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 minimum chi2 will be selected and the status will be tagged as an outlier

Member Typedef Documentation

using Acts::MeasurementSelector::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.

inline

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
