Comparison of results for our six initial simulations, corresponding to a late reionisation scenario, and for an additional seventh simulation, corresponding to an early reionisation scenario. Left panel: reionisation histories. Middle panel: patchy kSZ angular power spectra. The data point corresponds to constraints from Reichardt et al. (2020). Right panel: minimal size of ionised regions as a function of global ionised level. Shaded areas correspond to the 68% confidence level on kSZ amplitude propagated from the probability distributions of the fit parameters.
