FIG. 1. Pink and monochromatic data collection.

A. Ewald diagram for an exposure during a conventional monochromatic exposure during sample rotation (not to scale). Rotation of the sample corresponds to rotation of the reciprocal crystal lattice around its origin (black dot, right corner), sweeping out a corresponding section (orange) of the reflections (reciprocal lattice points). Reciprocal lattice points shown as fuzzy dots; observable reflections, which pass through the Ewald sphere, are shown as darker dots. Partially observed reflections are shown in pink. B. For monochromatic stills, few reflections are observable, and for those that are observed, intensities are only partially observed. C. The Laue method collects polychromatic stills using a range of wavelengths from ${\lambda }_{\text{min}}$ to ${\lambda }_{\max }$. As a result, more reflections are observed and mostly at their full intensity. Incident beam vectors $(S_0)$ shown in blue; scattered beam vectors $(S_1)$ in green. Variation in the length of $S_0$ and $S_1$ vectors in panel $\mathrm{C}$ indicates that these correspond to different wavelengths. Harmonics are indicated with arrowheads and lie on “central rays” which pass through the origin of the reciprocal lattice. Partials are rare and occur predominantly at low resolution—close to the origin of the reciprocal lattice.
