These conditions yielded a beam approximately 3 µm in diameter, delivering an electron flux of ~ 0.01 e -/Å 2 /s at spot size 11, 0.03 e -/Å 2 /s at spot size 10, and 0.045 e -/Å 2 /s at spot size 9. A 100 µm selected area aperture was used to sample from a ~1.2 µm radius circular area of the conjugate image plane. A virtual camera length of 420 mm yielded patterns that, as sampled by the Apollo detector, mapped a resolution of 0.8 Å at their edge. A camera length of 670 mm yielded patterns captured by the Apollo detector with a resolution of 1.4 Å at their edge. For comparison, data was also acquired using a Ceta-D detector mounted in line with the Apollo, on the same Talos F200C microscope; diffraction was recorded under the same beam conditions as for the Apollo. Due to the different positions of this detector relative to the specimen, a virtual camera length of 960 mm was necessary to capture patterns with a resolution of 0.8 Å at their edge. Diffraction was recorded as crystals were unidirectionally rotated at a fixed rate of speed, typically from 0.3 to 2 °/s. A standard tilt series spanned a 100-degree wedge of data, from +50 to -50 degrees. All crystals were aligned to eucentricity such that they remained within the selected area aperture during the entire tilt range.
