(a) Aluminium powder pattern recorded with oscillation of the rotation axis. Visible resolution rings are at 2.338, 2.024, 1.431 and 1.221 Å. (b) Fitting of strong reflections to ellipses. The elliptical distortions of the rings were determined as A/B = 1.0273 (2.338 Å), A/B = 1.0239 (2.024 Å), A/B = 1.0231 (1.431 Å) and A/B = 1.0231 (1.221 Å), where A and B are the major and minor axes, respectively.
