Due to a calculation error, the experimental data points (red/green circles) reported in figure 8 for D/D0 are incorrect, by a factor of exactly two. The same error is in the accompanying electronic supplementary material, Fig7_8_data_saxs.xlsx, column N. For example, the range of experimental values for figure 8a are displayed as D/D0 = 10–25, and this range should be D/D0 = 5–12. The accompanying theoretical calculations (lines in figure) are unchanged by this correction.
