Namespaces
namespace	Acts
	This class is not to needed in AthSimulation.
namespace	ActsTrk
	The AlignStoreProviderAlg loads the rigid alignment corrections and pipes them through the readout geometry to cache the final transformations of the sensor surfaces associated to one particular detector technology (Pixel, Sct, etc.).

Functions
std::array< double, 2 >	ActsTrk::cylinderIntersectPaths (const Amg::Vector3D &pos, const Amg::Vector3D &dir, const double cylinderR)
	Returns the two path lengths for a track state with position and direction to intersect the cylinder with radius R.
std::optional< Acts::BoundTrackParameters >	ActsTrk::expressOnCylinder (const Acts::GeometryContext &tgContext, const Acts::BoundTrackParameters &boundPars, const double cylinderR, const Acts::Direction dir=Acts::Direction::Forward())
	Propagates the track parameters to a cylinder with radius R and expresses them as bound track parameters.
std::vector< Acts::BoundTrackParameters >	ActsTrk::expressOnCylinders (const Acts::GeometryContext &tgContext, const Acts::BoundTrackParameters &boundPars, std::span< const double > cylinderRadii, const Acts::Direction dir=Acts::Direction::Forward())
	Propgate the track parameters to a set of cylinders.
