deviationFactors

template<typename propagator_t, typename actor_list_t = ActorList<>>

std::vector<double> Acts::RiddersPropagatorOptions< propagator_t, actor_list_t >::deviationFactors = {-2, -1, 1, 2}

Different factors applied to the initial scale to create the deviations of the individual bound track parameters.

The resulting function value deviations are then fitted to a line to determine the first order derivatives of the final parameters wrt. the initial parameters.
