We observe short-ranged correlations over the whole range of $\phi_\rm avg$ and anti-correlations for $\phi_avg>0.8277$. The spatial extent of the anti-correlation increases with $\phi_avg$ while the position of the maximum of the anti-correlation and the extent of the positive correlation shrink with $\phi_avg$. We speculate that the onset of anti-correlation corresponds to dilatancy onset in this system.
