template<typename generator_t >

using ActsFatras::SingleParameterSmearFunction = typedef std::function<Acts::Result<std::pair<double, double>>(double, generator_t&)>

Smearing function definition for single track parameters.

The function takes the unsmeared parameter and returns the smeared value and a standard deviation.

Template Parameters

generator_t The type of the random generator.

using ActsFatras::StandardChargedElectroMagneticInteractions = typedef InteractionList<detail::StandardScattering, detail::StandardBetheBloch, detail::StandardBetheHeitler>

Standard set of electro-magnetic interactions for charged particles.

Scattering must come first so it is computed with the unmodified initial energy before energy loss is applied.

Warning: The list has no cuts on input particle charge or kinematics, i.e. it relies on the simulator to preselect relevant charged particles before application.
