Figure 2
Top: Observed structure factor squared divided by calculated structure factor squared , plotted in bins from 0 to 1.5 Å−1 (Zavodnik et al., 1999, Zhurov et al., 2008). Middle: Fractal dimension plots (Meindl & Henn, 2008) of all datasets calculated from a 1 × 1 × 1 unit-cell cube of the electron density with 72 × 80 × 108 grid points along the a, b and c direction, respectively, for a uniform grid. Bottom: Residual density maps in the plane of the ring. Blue means that a higher electron density is observed than calculated, while red is lower electron density. The black dotted line is zero. Contours are shown at 0.1 e Å−3 intervals. Only atoms within a 0.2 Å distance of the plane defined by C1/C2/C3 are labeled in the plot. Both the fractal dimension plots and residual density maps are calculated at the largest common resolution cutoff at 1.17 Å−1 for a better comparison. |
