\caption{$1\sigma$ uncertainties on $H_0$ from GW memory Fisher analysis. Values of $\bar{\sigma}_{H_0}$ are the mean over seeds. Population scatter $\sigma_\mathrm{pop}$ (astrophysical spread across event realisations) and error on the mean $\sigma_\mathrm{err}$ (Monte Carlo accuracy) are available in the accompanying CSV but are not shown here for brevity.}
