Detailed Description

template<Acts::BoundIndices... kParameters>
struct ActsFatras::BoundParametersSmearer< kParameters >

Parameter smearer for fast digitisation for bound parameters

The logic of this smearer is the following:

• Input is a single simulated ActsFatras::Hit which is wrapped into
• It returns smeared parameter vector and a covariance matrix

Note

This smearer only supports uncorrelated smearing of parameters
