Blast-wave fit of $\pi^+$, K$^+$, p, d, and $\rm ^{3}He$ particles for 0-20% centrality for Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV. Solid symbols denote the $p_{\rm T}$ range of the spectra used forthe fits, while the open symbols show the remaining part. The lower panels show the deviations of the measured spectra to the BW fits.
