Autocorrelation function (as derived from the dark-field extinction coefficient) for the 50 nm disk sample (blue), as well first and third quartile bounds, which reveal the noisy nature of this signal. The yellow graph show the autocorrelation function for the 150 nm disk sample. Notice how the initial slope is shallower than for the 150 nm autocorrelation function.
