Bound (7) on the variance discrepancy, $|\Delta^2\hat{\phi}^{\prime}-\Delta^2\hat{\phi}|$, against $\phi$ ($^\circ$), for the same depolarising channel (bottom panel), evaluated with $\epsilon_0 = \epsilon$ as the printed curve is. The discrepancy itself is identically zero for this channel, so the bound is the only curve in the printed panel.
This panel was computed from the analytic model published in the paper. The plot shown here is re-rendered for interactive viewing and analysis. See the paper for the original figure and full scientific context.
