Bell parameters that best fit these experimental unfolding histograms
(\cref{sec:sawsim:rate:bell,sec:sawsim:results:fitting}). The results
in \cref{fig:calcium:valley} show that the best fit for standard PBS
-was with $\Delta x_u = TODO\U{nm}$ and $k_{u0}=TODO\U{s$^{-1}$}$. In
-the \Ca\ buffer, the best fit was with $\Delta x_u = TODO\U{nm}$ and
-$k_{u0}=TODO\U{s$^{-1}$}$.
+was with $\Delta x_u=0.132\U{nm}$ and $k_{u0}=0.222\U{s$^{-1}$}$. In
+the \Ca\ buffer, the best fit was with $\Delta x_u=0.123\U{nm}$ and
+$k_{u0}=0.450\U{s$^{-1}$}$.
