Both $\\pi^+$ and $K_S^0$ show negative $v_1$ slope at low $p_T$ ($p_T < 0.6$ GeV/$c$). Collision energy dependence of $v_1$ slope and $p_T$-integrated $v_2$ for $\\pi^{\\pm}$, $K_S^0$, and $\\Lambda$ are also presented. A comparison to JAM model calculations indicates that spectator shadowing can lead to anti-flow at low $p_T$.
