Dependence of the standard deviation of the $\delta\pt$ distributions on uncorrected charged particle multiplicity, compared to the limit derived from the measured track $\pt$ spectrum (Eq. 3) and from additional elliptic and triangular flow contributions (Eq. 4) $R = 0.4$, ${p_{\rm t}^{\rm min}}$ = 0.15 GeV/c
$$\begin{align*} (3)   $\sigma(\delta{\pt}) = \sqrt{N_{\rm A} \cdot \sigma^2(\pt) + N_{\rm A} \cdot \langle \pt \rangle^2}$    (4)    $\sigma(\delta{\pt}) = \sqrt{N_{\rm A} \cdot \sigma^2(\pt) + \left(N_{\rm A} + \sigma^2_{\rm NP}{(N_{\rm A})}\right) \cdot \langle \pt \rangle ^2} \end{align*}$$
