Transverse momentum distributions of $\pi^{+}$, $\rm K^+$, p , $\rm K^{0}_{S}$ and $\Lambda$ , and the $\phi$ meson  for the 0--5\% and 80--90\% centrality intervals in Pb--Pb collisions at $\sqrt{s_{\rm{NN}}}= 2.76$ TeV. The data points are scaled by various factors for better visibility. Statistical and systematic uncertainties are shown as bars and boxes, respectively.
