$v_2$ in high-multiplicity p--Pb collisions compared with AMPT calculations. $p_{\rm T}$-differential $v_2$ measured with two-particle correlation for mesons ($\pi^\pm$, ${\rm K}^\pm$, ${\rm K}^0_{\rm S}$) and baryons (${\rm p}^+\bar{\rm p}$, $\Lambda+\bar{\Lambda}$) in high-multiplicity p--Pb collisions at $\sqrt{s_{\mathrm{NN}}} = 5.02$ TeV. Horizontal bars (boxes) represent the statistical (systematic) uncertainties. Comparison with the calculations from the AMPT String-melting model  is also presented. The AMPT curves are obtained by applying the same template fit method to the correlation distributions as used in the data analysis. Only statistical uncertainties are shown for the AMPT calculations.
