Reconstruct vertices, but exploit the fact that you know that some tracks cannot come from a secondary vertex. primaries Tracks that cannot come from a secondary vertex (but can, in principle, be non-primaries, also). tracks These are the tracks that are of unknown origin. These tracks are subjected to pattern recognition. spot A beamspot constraint is mandatory in this method.

Reimplemented from VertexReconstructor.
