FIG. 4:

The average of the autocorrelation $\langle {\nu }_q\left(t\right){\nu }_q\left(0\right)\rangle$ over similar modes for the simulation (solid) and fits (dashed). POPC is colored in black. The $\Delta c_{\text{PE}}=0.28{\text{nm}}^{-1}$ is colored red. The shaded regions indicate two standard errors from the simulation obtained by averaging over similar modes. The label at $t=0.2\text{\hspace{0.17em}s}$ on all three plots is shown in bold for a common reference. Here $\kappa =33.8k_{\text{B}}T$ and $D=8\mu {\text{m}}^2/\text{s}$.
