Figure 3
Autocorrelation functions plotted as a function of the time delay τ from the XPCS analysis and speckle contrast factors as a function of the integration time T from the XSVS analysis over three q rings of pixels (a) at q = 2.63 × 10-3 Å−1, (b) at q = 2.74 × 10-3 Å−1 and (c) at q = 2.95 × 10-3 Å−1. The experimental (empty circles) are fitted by equation (3) (solid line) for the XPCS analysis. The experimental (filled circles) are fitted by equation (13) (dashed line) for the XSVS analysis. Note that the horizontal axis is labeled as `Time' for simplicity but has different meanings for the two methods. |
