using ActsFatras::detail::SmearFunction = typedef std::function<Acts::Result<std::pair<double, double>>(double)>

Smearing functions definition:

• it takes the unsmeared parameter
• it returns the smeared parameter and a covariance

using ActsFatras::detail::StandardBetheBloch = typedef Process<BetheBloch, EveryInput, SelectPMin, EveryParticle>

Ionisation/excitation energy loss with a lower p cut on output particles.

Bethe-Bloch generates no particles and the child selector has no effect.

using ActsFatras::detail::StandardBetheHeitler = typedef Process<BetheHeitler, AsInputSelector<SelectElectronLike>, SelectPMin, EveryParticle>

Electron Bremsstrahlung energy loss with a lower p cut on output particles.

Only applies to electrons and positions. Bethe-Heitler generates no particles and the child selector has no effect.
