Figure 19
(a) 3 Å resolution Fourier image of a C atom with B factor 50 Å2 (blue) and its second derivative (brown); the image is spherically symmetric and is represented by a one-dimensional radial distribution. The atom radius is defined as twice the distance from the center of the atom to the first inflection point of this curve. (b) Radius as determined in (a) for the C atom as a function of resolution, shown for several B-factor values.
