The goal of this study has been to establish a set of multiplicity cuts
which best correlate with given impact parameters. In order to achieve
this, we have measured the trigger cross section for the minimum
bias runs for all four beam energies. We assume that the multiplicity
monotonically increases with centrality (a pretty safe assumption) and
that there is a strong correlation between Multiplcity and impact
parameter (not such a safe assumption).
