  Recently it has been shown that calculations based on a hadronic rescattering
model agree rather well with experimental results from the first RHIC run.
Because of the large particle densities intrinsically present at the early time
steps of Monte Carlo calculations attempting to model RHIC collisions
undesirable artifacts resulting in non-causality may be present. These effects
may compromise the results of such calculations. The subdivision method, which
can remove such artifacts, has been used to test the present rescattering model
calculations. It is shown that no appreciable changes are seen in the present
calculations in using the subdivision method, thus strengthing the confidence
in the results of this rescattering model for RHIC.
