I feel like this plot could be made more impactful by reducing the covariance in the prior states, or by making the sensor models more noisy. This is something that's subjective though, so feel free to ignore me!

[nperree-dstl]

Is this for the uncertainty metric graph? Good point, I may also remove the OSPA one as it doesn't show anything useful

[hpritchett-dstl]

Yes, the uncertainty metric plot.
