The kSZ maps from the simulations: f2000 (top left), f250 (top right), f2000C (middle left), f250C (middle right), instant reionization at ﹩z_{\mathrm{instant}\,}=13﹩, which gives the same total electron scattering optical depth as simulation f250 (bottom left), and spatially uniform reionization with the same reionization history and thus the same total electron scattering optical depth as simulation f250 (bottom right).
