Abstract
The charged particle multiplicity distributions measured by two experiments, WA97 and NA57, in Pb+Pb collisions at $158\,A\,\mathrm{GeV}/{\it c}$ have been analyzed in the framework of the Wounded Nucleon Model (WNM). We obtain a good description of the data within the centrality range of our samples. This allows us to make use of the measured multiplicities to estimate the number of wounded nucleons of the collision.
