Struct Documentation

template<Acts::FreeIndices... kParameters>
struct ActsFatras::FreeParametersSmearer

Generic implementation of a smearing meathod for free parameters.

Template Parameters

• kParameters: parameter pack describing the parameters to smear

Public Functions

template<typename generator_t>
Acts::Result<Acts::ParameterSet<Acts::FreeIndices, kParameters...>> operator()(const SmearInput &sInput, generator_t &sRandom, const std::array<SmearFunction<generator_t>, sizeof...(kParameters)> &sFunctions) const

Smearing function.

Note

uncorrelated smearing of the direction using the components is not recommended

Return

Smeared free parameter set wrapped in a Result<…> object

Template Parameters

• random_gnerator_t: The type of the random generator provided

• kParameters: parameter pack describing the parameters to smear

Parameters

• sInput: The smearing input struct with the simulated hit

• sRandom: The smearing random number gnerator

• sFunctions: The smearing functions that are applied
