+\maketitle
+
+The reproduction of the magnetic noise in \cite{QubitRelax} is below, in \cref{fig:lukemag}.
+The important point for reproducing the figure in Luke's paper is that I did not use the expression for $r_s$ there.
+Instead, I used eqs 2.20 and 2.26 in Ford-Weber\cite{Ford1984}:
+
+\begin{align}
+\zeta_s(u) &= 2 i \int_0^\infty \dd{y} \frac{1}{\epsilon_t(\sqrt{u^2 + y^2}) - u^2 - y^2} \\
+r_s(u) &= \frac{\zeta_s(u) - \frac{\pi}{i u}}{\zeta_s(u) + \frac{\pi}{i u}},
+\end{align}
+up to a constant out front which I pulled to outer code.
+
+Additionally, the other important thing is that every parameter in the caption of Luke's figure 3 are are actually in radians per second, except for $\nu$ (I think).
+The collision frequency $\nu$ is the odd one, because in the expression for $\epsilon$, the local limit reduces to the Drude case precisely with $\tau = \frac{1}{\nu}$.
+I was always under the impression that the Drude $\tau$ just carried units of seconds, rather than seconds per radian, but now I'm not sure (there are after all $\tau \omega$ terms which don't look ``unitless'').
+That all implies that $\tau = \left(6 \pi \right)^{-1} \times \SI{e-12}{\s}$.
