Figure 4

(a) Fourier coefficient sn(q) of the single-particle diffraction pattern, extracted from the experimental CCs, as a function of q. The data are shown for n=6, 12, 18, 24, 30, and are rescaled with s0(q). The continuous and dashed curves correspond to the real and imaginary parts, respectively. (b) Complex plane representations of the ratios Rnm(qa,qb,qc) (equation (13)), for different n and m multiples of 6, for fixed qa=0.066 nm−1 and qb=0.115 nm−1, and for a large number of qc. The centroid point in orange is the median of all points, and the orange circle encloses the area containing the closest 80% of all points. The imaginary part of the centroid point is negligible, and its real part corresponds to , with . (c) Single-particle diffraction pattern S(q,φ), on a logarithmic colour scale, and defined over a disk-shaped region with maximal reciprocal-space frequency qmax=0.24 nm−1. The dark regions in the corners are deficient of data. The red bar corresponds to q=0.1 nm−1.
