Figure 6
Example of the problematic nature of discretization effects in azimuthal averaging of 2D detector images. The left image shows all pixels in an example image that contribute to the azimuthal integration of a single radial element, where the red box highlights the region of interest. Here, integration within the geometrically defined radial segment (dashed blue lines) causes artefacts as in some cases it is not clear which pixels to count in- or outside of the integration area. Oversampling mitigates this issue, as non-binary weighting values allow that a single pixel can be considered for two radial segments but with corresponding weight.
