Fig. 2.

Epidemic impact against ring-cull radius for epidemics in (A) Cumbria and (B) Lancaster County. In both figures, the blue line shows the mean epidemic impact for simulations using the true location data while the red line shows the mean epidemic impact for the reparameterized random data. Both lines are calculated as locally smooth splines fit to 10,000 simulation results. (C) Farm network and (D) mean epidemic impact against ring-cull radius for the random data (red line) and the true data (blue line). For (C) and (D), S₀ = 4, N = 1,000, and B = 0.4. In (A), (B), and (D), the black dots show the minima of each line.
