Detailed Description

template<typename generator_t, size_t kSize>
struct ActsFatras::BoundParametersSmearer< generator_t, kSize >

Uncorrelated smearing algorithm for fast digitisation of bound parameters.

Template Parameters

generator_t	Random number generator type
kSize	Number of smeared parameters

The smearer takes a single simulated Hit and generates a smeared parameter vector and associated covariance matrix.
