Figure 2
Defocusing length [\overline{FD}] and blurring B versus goniometer angle θ and distance from the detector centre d. (a) shows the angular dependence of the defocusing length for several positions on the detector. (b) shows the variation of [\overline{FD}] on the detector for fixed goniometer position. The inset shows a zoom to the high-angle curve. (c) shows the angular dependence of the blurring, while (d) shows the variation of B along the detector for certain fixed angles. (c) and (d) are shown for variable slits (full lines) and fixed slits (dashed lines). The parameters used for the calculations are L = 330 mm, [\alpha = 0.44]° and [S_0 = \infty] for the fixed-slit case and S = 12 mm in the case of variable slits.
