template<typename vfitter_t , typename sfinder_t >

bool Acts::IterativeVertexFinder< vfitter_t, sfinder_t >::Config::createSplitVertices = false

Assign a certain fraction of compatible tracks to a different (so-called split) vertex if boolean is set to true.

template<typename vfitter_t , typename sfinder_t >

double Acts::IterativeVertexFinder< vfitter_t, sfinder_t >::Config::cutOffTrackWeightReassign = 1

If reassignTracksAfterFirstFit is set this threshold will be used to decide if a track should be checked for reassignment to other vertices
