Figure 2
Harker section (w = 0) for the Xe derivative. The twin fraction of the derivative data is 0.45 and that of the native data is 0.14. The difference Patterson function calculated using twinned data is displayed in pink and shows a set of peaks which do not correspond to a heavy-atom site. The difference Patterson function for which detwinned data is used is coloured blue. The peaks that were present when twinned data was used have disappeared; instead, a set of peaks related to the true xenon-binding site has emerged. |
