Detailed Description

Author: N. Giacinto Piacquadio (University of Freiburg); Kirill Prokofiev Kiril.nosp@m.l.Pr.nosp@m.okofi.nosp@m.ev@c.nosp@m.ern.c.nosp@m.h

First real implementation: August 2006

Dummy vertex smoother. Does not refit trajectories with the knowledge of the vertex. Instead it takes trajectories, extrapolate them to the transverse point of the closest approach to the reconstructed vertex and calculates the perigee parameters of trajectories with respect to that vertex.

The extrapolated perigee parameters w.r.t the reconstructed vertex are then stored in m_perigeeAtVertex datamembers of VxTrackAtVertex's.

◆ sysInitialize()
