Detailed Description

template<class particle_hypothesis_t>
class Acts::GenericBoundTrackParameters< particle_hypothesis_t >

Track parameters bound to a reference surface for a single track.

Template Parameters

particle_hypothesis_t Helper type to interpret the particle charge/momentum

This is intended as a user-facing data class that adds additional accessors and charge/momentum interpretation on top of the pure parameters vector. All parameters and their corresponding covariance matrix are stored in bound parametrization. The specific definition of the local spatial parameters is defined by the associated surface.

Note: This class holds shared ownership on its reference surface.

Constructor & Destructor Documentation

template<class particle_hypothesis_t>

Acts::GenericBoundTrackParameters< particle_hypothesis_t >::GenericBoundTrackParameters	(	std::shared_ptr< const Surface >	surface,
		const ParametersVector &	params,
		std::optional< CovarianceMatrix >	cov,
		ParticleHypothesis	particleHypothesis
	)

inline

Construct from a parameters vector on the surface and particle charge.

Parameters

surface	Reference surface the parameters are defined on
params	Bound parameters vector
cov	Bound parameters covariance matrix
particleHypothesis	Particle hypothesis

In principle, only the charge magnitude is needed her to allow unambiguous extraction of the absolute momentum. The particle charge is required as an input here to be consistent with the other constructors below that that also take the charge as an input. The charge sign is only used in debug builds to check for consistency with the q/p parameter.

friend

Compare two bound track parameters for bitwise equality.

Note: Comparing track parameters for bitwise equality is not a good idea. Depending on the context you might want to compare only the parameter values, or compare them for compatibility instead of equality; you might also have different (floating point) thresholds of equality in different contexts. None of that can be handled by this operator. Users should think really hard if this is what they want and we might decided that we will remove this in the future.
