Distributions of ΔF values. (a) Histogram of ΔF values obtained from the first 360° wedge collected on crystal A (blue bars), {ΔF}1, fitted with a Gaussian (dashed line); fitting parameters are shown in the inset. Note that the fraction of ΔF values outside the interval [−3, +3] (not shown in the graph) is less than 0.1% of the total number of the ΔF values. (b) Gaussians obtained by fitting the frequency distributions obtained for {ΔF}1 to {ΔF}15, respectively, using colour codes defined in the inset. The functions used for fitting are defined in §2.9. |
