However, for the strange loops there is no strange connected contribution as there are no valence strange quarks. Similarly, we cannot just use the fit results solely from the disco loops due to the fact that at \nu = 0 (which is 3 of the 4 terms) the value
of the disco loop fits is 0. In order to visualize the results of the strange loops, I did use the connected isoscalar light quark matrix elements in place, which is what is in the plot sent with this. Using this method should have the same multiplicative
renomalizable factors (at least the parts due to the Wilson line as it is using the same shaped Wilson lines) but the normalization may be very off.</div>

Thank you. I am happy to share strange disco results if those are ready, but I was not planning to mention that in the abstract, in case they aren't. I figured just leaving "isoscalar quark" is broad enough to cover both cases.</div>
