These are consistent with being caused by correlations due to jets at large $p_T$, where the measured suppression must be included to reproduce the centrality dependence of the non-random fluctuations.4 pages, 4 figures, contribution to the proceedings of the 17th International Conference on Ultra-Relativistic Nucleus-Nucleus Collisions (Quark Matter 2004), to appear in Journal of Physics GNuclear Experimenttext
