BoundParametersSmearer
¶ 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
