Blast-wave fits to the \vtwo(\pt) of pions, kaons, and protons and predictions of the deuterons \vtwo(\pt) for the centrality intervals 10--20$\%$ (left) and 40--50$\%$ (right). In the lower panels, the data-to-fit ratios are shown for pions, kaons, and protons as well as the ratio of the deuterons \vtwo to the \mbox{blast-wave} predictions. Vertical bars and boxes sent the statistical and systematic uncertainties, respectively. The dashed line at one is to guide the eye.
