Figure 4
(a) 2D histogram of fibroblast growth factor at 1.6 Å with 0, 40 and 90° phase errors. These 2D histograms differ significantly showing that the 2D histogram is very sensitive to phase error. (b) One-dimensional density histogram of fibroblast growth factor at 1.6 Å with phase errors from 0 to 90° in a 10° step. There is a large variation between these ten density histograms showing that the density histogram is dependent on phase error. (c) One-dimensional gradient histogram of fibroblast growth factor at 1.6 Å with phase errors from 0 to 90° in 10° steps. All ten gradient histograms differ significantly. This shows that the phase error affects not only the density distribution but also the gradient distribution.
