Elliptic flow integrated over the $p_{\rm t}$ range $0.2< p_{\rm t}< 5.0$ GeV/$c$, as a function of event centrality, for the 2- and 4-particle cumulant methods, a fit of the distribution of the flow vector, and the Lee-Yang Zeroes method For the cumulants the measurements are shown for all charged particles (full markers) and same charge particles (open markers) Data points are shifted for visibility RHIC measurements for Au-Au at $\snn = 200 $GeV, integrated over the $p_{\rm t}$ range $0.15< p_{\rm t}< 2.0 $GeV/$c$, for the event plane
$v_2\{{\rm EP}\}$ and Lee-Yang Zeroes are shown by the solid curves
