Friedel pair identification in a s3DXRD dataset. (a) Possible pairs are found in symmetric scans acquired at opposite y translation [-t_{y}] and +ty from the rotation center [(y = 0)]. (b) [\omega\, (\bmod\ {360})] versus [\eta\, (\bmod\ {360})] for a subset of paired peaks from symmetric scans (×: [d_{y} = -1.5]; +: [d_{y} = +1.5]) in sample WGSI3, after transforming [(\omega,\eta)] coordinates of the subset [\{d_{y} = -1.5\}] to make paired peaks overlap. Peaks are colored by Friedel pair index, a unique identifier for each pair in the dataset. Thus, two peaks forming a correct Friedel pair appear as overlapping `×' and `+' symbols of the same color. Spot size depends on log(intensity). Overall, there is a good match of Friedel pairs in ω and η. Isolated data points belong to unreliable pairs, where two peaks with very different [(\omega,\eta)] coordinates were associated together.
