Hi,

Regarding the unwelcome correlation discovered by Flemming,
I've attached a plot of "BB Multiplicity vs. Vertex difference for
Matched (magnet+tof) Tracks" showing the correlation more clearly.
The BB multiplicity was calculated by the BB Rdo Module.
One of the problems with this correlation is cutting out central events
by requiring a matching between a BB vertex and a track vertex, unless
we use a wide cut or multiplicity dependent offsets (yuck!) for BB-vertex.
