Figure 4
Templates of local density calculated at a resolution of 2.6 Å. The templates are arranged in order of decreasing contribution to the information about the density at the central point. The sections shown are 8 × 8 Å; only the spherical region 4 Å in diameter at the center of each figure is used in the pattern-matching process. Contours at +1.5σ (a) and −1.5σ (b, templates in the same orientation as in a) are shown. |
