Combined CMS and TOTEM data at $\sqrt{s}=8\text{TeV}$ [50] for the charged-particle distribution $\mathrm{d}{\mathrm{N}}_{\text{ch}}/\mathrm{d}\mathit{\eta }$, in inclusive inelastic (top left), NSD-enhanced (top right), and SD-enhanced (bottom) pp collisions. The data are compared to pythia6 using CUETP$6$S$1$-CTEQ$6$L1, and to pythia8 using CUETP$8$S$1$-CTEQ$6$L1, CUETP$8$S$1$-HERAPDF1.5LO, and CUETP$8$M$1$. The bottom panels of each plot show the ratios of these predictions to the data, and the green bands around unity represent the total experimental uncertainty
