Table 1.

Average charged-particle pseudo-rapidity density, ${⟨\mathrm{d}{N}_{\mathrm{ch}}/\mathrm{d}{\mathit{\eta }}_{\mathrm{lab}}⟩}_{|\mathit{\eta }|<0.5}$, measured at mid-rapidity in visible cross section event classes and average number of colliding nucleons, $⟨{\mathrm{N}}_{\mathrm{coll}}⟩$. Multiplicity classes are defined using the V0A estimator [48, 49], as described in the text. Total systematic uncertainties are reported, see [49] for details, which do not include the difference with respect to the other methods used to estimate the average $N_{\mathrm{coll}}$. For minimum bias collisions, $⟨\mathrm{d}{N}_{\mathrm{ch}}/\mathrm{d}{\mathit{\eta }}_{\mathrm{lab}}⟩$ $=$ 16.81 $\pm$ 0.71 and $⟨{\mathrm{N}}_{\mathrm{coll}}⟩$ $=$ 6.87 $\pm$ 0.5
