Elliptic flow of (anti-)$^{3}$He in comparison with the predictions from the Blast-Wave model and a simple coalescence approach for the centrality classes 0--20$\%$ (left), 20--40$\%$ (middle), and 40--60$\%$ (right). The lower panels show the differences between data and models for each centrality range. The statistical uncertainties of the data and the model are added in quadrature. Vertical bars and boxes represent the statistical and systematic uncertainties, respectively. | |
