Experimental PDF results. (a) A gapped, and correspondingly reconstructed, pattern collected at the European XFEL source in a multi-JUNGFRAU-detector setting for ZnO nano-particles. The two insets show, in red, the reconstructed data regions. Plotted data correspond to a single 30 fs shot across all detectors. (b) Reconstruction was performed for [k_{\rm c} = 79], identified as locally optimal by all three performance metrics. (c) S(Q) was calculated for both the reconstructed (red) and gapped (black) patterns, setting gap regions to zero in the latter. (d) The corresponding F(Q) functions show significant effects in the gapped case, due to the zeroed regions in S(Q). Resultant G(r) functions show (e) extreme artifacts in the gapped case, especially for the low-r region, while (f) every major feature of the theoretical PDF (red) is present in the PDF corresponding to the reconstructed experimental data (blue). Remaining low-r artifacts might be attributed to multi-detector normalization issues and data quality.
