"Figure 3a-3" of "Elliptic flow for $\phi$ mesons and (anti)deuterons in Au+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV"

$v_2$ vs $KE_T$ for several identified particle species obtained in mid-central Au+Au collisions, and ${v_2}/{n_q}$ vs ${KE_T}/{n_q}$ for the same particle species.针对半中心金-金（Au+Au）碰撞中获取的若干已鉴别粒子种类，给出其$v_2$随$KE_T$的变化关系；同时针对同种粒子，呈现$v_2/n_q$随$KE_T/n_q$的变化关系。
