Relative yield of inclusive \jpsi mesons as a function of relative charged-particle pseudorapidity density in comparison to D mesons (average of D$^0$, D$^+$, and D$^{*+}$ species), for the \pt  interval 2-4 \gevc   The error bars show the statistical uncertainties, the boxes the systematic ones (for the D mesons, additional systematic uncertainties due to the b feed-down contributions and the event normalisation are not shown)
