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).
