Figure 2
SIR probabilistic Harker diagram (notation as in Fig. 1 ![[link]](../../../../../../logos/arrows/d_arr.gif) ). (a) Contour plot showing components of the PDF. The component arising from the native is shown in black contours and the component arising from the derivative is shown in red contours centred on H1 (the point at the base of the red arrow). The dashed black and red circles indicate the measured values of the observed structure-factor amplitudes for the native and the derivative, respectively. (b) The PDF [the product of the two components in (a)] is shown in dark red contours. The `best F' FB is shown as a black arrow. (c) Three-dimensional plot of the value of the PDF. The likelihood is the volume under the PDF surface. (d) Plot of the likelihood as a function of the occupancy of the substructure (increasing amplitude of H1). The maximum likelihood is marked with a dot. All other panels in this figure show the values of the parameters at the point of maximum likelihood. (e) The PDF for the phases of the true structure factor F is shown in red and the PDF reconstructed from the four Hendrickson–Lattman (Hendrickson & Lattman, 1970) coefficients (HL) is shown as a black curve. (f) Bar chart showing the relative values of the four HL coefficients A, B, C and D. |
