Figure 2
Zoom around a few reflections in the twofold diffraction plane, taken with a sample-to-detector distance equal to 414 mm, allowing a higher Q-resolution without attenuation. The first panel (top left) displays the reciprocal space spanned in this configuration, together with the two- and fivefold axes orientations. Then, from top left to bottom right are Bragg peaks that lie on a fivefold axis (18/29 and 7/11), a twofold axis (20/32 and 8/12) and a threefold axis (6/9). All panels are the same size: 1.66 nm−1 wide and 1.84 nm−1 high. The colour coding and the logarithmic scale are chosen to highlight the weak reflections: first a grey scale for very weak counts, followed by a temperature scale. Pixels with intensity larger than 106 counts are indicated in blue.
