Detailed Description

template<typename vfitter_t>
class Acts::ZScanVertexFinder< vfitter_t >

Implements a vertex finder based on the mode of z0 values:

Determines the mode value of all input track z0 values
If no constraint is given, returns (0,0, z0_mode) as vertex position
If vertex constraint is given with x=x_constr and y=y_constr, the returned vertex position will be (x_constr, y_constr, z0_mode).
