$v_{0}(p_\mathrm{T})$ of pions ($\pi^{\pm}$), kaons ($\mathrm{K}^{\pm}$), and protons ($\mathrm{p}(\bar{\mathrm{p}})$) scaled by number of constituent quarks ($n_q$) shown as a function of transverse kinetic energy per constituent quark, $(m_\mathrm{T}-m_{0})/n_{q}$ in Pb$-$Pb collisions at $\sqrt{s_\mathrm{NN}} = 5.02$ TeV for centrality intervals 10$-$20\% (a), 30$-$40\% (b), and 60$-$70\% (c). The line represents a third-order polynomial function fitted to the pion data.
