Figure 3
The centres of distortions refined against tens of 3D ED datasets for diffraction lens excitations equal to eucentric focus (green), 102.8% of the eucentric focus (orange) and 105.6% of the eucentric focus (blue) for camera lengths of 1000 mm (empty circles) and 1200 mm (full circles). The average position is marked by a red dot. The physical pixel size is 7.4 × 7.4 mm and the number of pixels is 1024 × 1024. The outer red rings mark distances of 0.03 Å−1 from the average position of the distortion centre for the two camera lengths.
