Figure 3
v = 0 section of a native Patterson map calculated using data to 2.5 Å resolution showing the presence of a strong non-origin peak at coordinates (1/2, 0, 1/2) consistent with pseudo-B-centring. Contour levels are drawn every 10 map r.m.s.d. units between 5 and 100 r.m.s.d. units. The section is drawn between 0 ≤ u ≤ 1 and 0 ≤ w ≤ 1 and the asymmetric unit is outlined in red. |
