"Figure 3 (left)" of "Energy and system-size dependence of two- and four-particle $v_2$ measurements in heavy-ion collisions at RHIC and their implications on flow fluctuations and nonflow"

The LS and CI four-particle cumulant $v_2{4}^4$ for Au+Au collisions at 200 and 62.4 GeV for $0.15 < pT < 2.0$ GeV/$c$. The systematic errors are shown as narrow lines with wide caps at the end and statistical errors are shown as thick lines with narrow caps at the end. Statistical errors are not visible for most of the points.
