Code for running benchmarks on noisy observations

[jarnefeltoliver]

I am interested in running benchmarks on noisy observations as described in section 5.2 of https://arxiv.org/abs/1910.01741.
The code for this part would be greatly appreciated as it apparently is missing from the repo at the moment.
