CDF data at $\sqrt{s}=900\text{GeV}$ [11] on particle (top) and $p_{\mathrm{T}}^{\mathrm{sum}}$ densities (bottom) for charged particles with $p_{\mathrm{T}}>0.5\text{GeV}$ and $|\mathit{\eta }|<0.8$ in the TransMIN (left) and TransMAX (right) regions as defined by the leading charged particle, as a function of the transverse momentum of the leading charged-particle $p_{\mathrm{T}}^{\max }$. The data are compared to the herwig++ Tune UE-EE-$5$C and CUETHppS$1$. The green bands in the ratios represent the total experimental uncertainties
