"Figure 5" of "Fluctuations of charge separation perpendicular to the event plane and local parity violation in sqrt(sNN)=200 GeV Au+Au collisions at RHIC"

(Color online) Three-point correlator, Eq. 1, measured with $1^{st}$ and $2^{nd}$ harmonic event planes versus centrality for Au+Au collisions at $\sqrt{s_{NN}}$= 200 GeV. Shown with crosses are our previous results from the 2004 RHIC run (Y4) [9, 10]. The Y4 run used a second harmonic event plane. Y4 and Y7 $\Psi_{2}$ results are consistent within statistical errors. Shaded areas for the $2^{nd}$ harmonic points represent the systematic uncertainty of the event plane determination. Systematic uncertainties for the $1^{st}$ harmonic points are negligible compared to the statistical ones shown.
