(a) Three surface intersection spots (arrow) between the 420 dark cone and Ewald sphere (S-rings) and a spherical shell of radius [\sqrt{8}] (mesh surface) standing for mosaicity around the [{\overline 2}02] node. S-rings 1 to 7 correspond to changes in the incidence angle ω0 = θhkl with h = k = l varying from 2.17 to 2.23 in steps of 0.01, Φ0 = −134.56° and Φ = Φ0 + 180°. (b) Theoretical (red spheres) and experimental (blue cubes) intersection spots of the S-rings with the shell of grain misorientation. Projections of the interception points on the HK, HL and KL planes (open circles and open rectangles in dark grey) are also shown.
