"Figure 9.4" of "Collision Energy Dependence of Moments of Net-Kaon Multiplicity Distributions at RHIC"

Collision centrality dependence of the $S\sigma$ for $\Delta N_k$ distributions in Au+Au collisions at 27 GeV. The error bars are statistical uncertainties and the caps represent systematic uncertainties.

27 GeV 下金金（Au+Au）碰撞中ΔN_k分布对应的Sσ的碰撞中心度依赖关系。误差棒代表统计不确定度，误差帽则代表系统不确定度。
