Figure 2: Determining the signs of partial scattered intensities.
From: Single-particle structure determination by correlations of snapshot X-ray diffraction patterns
(a) R-factor monitoring agreement between spherical harmonics expansion coefficients of the squared scattered intensity computed in two distinct ways for all possible sign combinations assigned to the first 13 non-vanishing partial scattered intensities with l>0. The arrow marks the point corresponding to the correct sign combination. (b,c) Comparison of the expansion coefficients of the squared scattered intensity calculated from pair and triple correlations, respectively. Each row corresponds to the different l, indicated on the vertical axis, and magnitude is encoded with colour.
