Figure 1

The $\pT$-differential $\langle{M}\rangle\langle{\langle{\vec{u}_{n}\cdot\frac{\vec{Q}^{*}_{n}}{M}}\rangle}\rangle$ of pions (left column), kaons (middle column) and protons (right column) for minimum bias pp and 0-1%, 20-30% and 40-50% centralities in Pb-Pb collisions at $\sNN$. The rows represent different harmonics.
