An estimation of dynamic properties by fitting experimental autocorrelations to the correlation diffusion equation (CDE). (a) Representative fits of the experimental data to CDE for short (left) and long (right) source-collector separations $(\rho )$ . The vertical purple line denotes the end of the fitting window (which is the last lag time used for fitting). (b) The values of $\alpha D_B$ are plotted for various values of $\rho$ and ${{\mu }_s}^{\mathrm{\prime }}$ . The horizontal purple line denotes the mean value, $⟨\alpha D_B⟩$ , while the dashed purple lines denote the region $⟨\alpha D_B⟩\pm 1.96{\sigma }_{\alpha D_B}$ , where ${\sigma }_{\alpha D_B}$ is the standard deviation of $\alpha D_B$ .
