"Figure 12b" of "Systematic study of charged-pion and kaon femtoscopy in Au$+$Au collisions at $\sqrt{s_{_{NN}}}$=200 GeV"

Oscillation amplitudes relative to the event plane for charged kaons, shown as value $\pm$ statistical uncertainty $\pm$ systematic uncertainty for the 0%–20% and 20%–60% centrality bins.针对0%–20%与20%–60%碰撞中心度（centrality）区间的带电K介子（charged kaons），其相对于事件平面（event plane）的振荡振幅以数值±统计不确定度±系统不确定度的形式展示。
