Uncertainty predictions for <i>N</i> = 7.

The figures show the uncertainty of the predictions made by using 1PD, 12PD and 123PD from Fig 8 respectively. We see that 1PD has a very high average uncertainty and has a high uncertainty in almost the whole country. Using 12PD reduces that average uncertainty a lot, but there are still large areas with high uncertainty. By adding 3PD we see that these areas with high uncertainty are greatly reduced, resulting in an even lower average uncertainty.
