(Anti)deuteron $v_2$ measured at $|y| < 0.5$ in the centrality classes 0$-$20$\%$ (left) and 20$-$40$\%$ (right) in comparison with the Blast-Wave predictions obtained from simultaneous fits of the $p_{\rm T}$ spectra and $v_2$ of pions, kaons, and protons. Statistical and systematic uncertainties are represented by bars and boxes, respectively.
