and azimuth, consistent with local charge conservation (suppression of net-charge fluctuations). The vertical axis limits common to all panels were chosen to enhance the visibility of structure at large angular separations as opposed to showing the full depth of the negative peak at $\phi_\Delta = \eta_\Delta = 0$. Note that no CD (charge-dependent) component of elliptic flow is observed at the sensitivity level of these data. 1D projections of Fig. \[Figure2\] distributions and their 2D model fits (discussed below) onto individual difference variables $\phi_{\Delta}$ and $\eta_{\Delta}$ are shown in Fig. \[Figure3\]. Solid dots and curves (open triangles and dashed curves) correspond to $\eta_{\Delta}$ $(\phi_{\Delta})$ projections. The projections are over the pair acceptances apparent in Fig. \[Figure2\].
