Figure 5.

The shifts in predicted reflection positions on a mid-resolution panel at the start (left), after Euclidean movements (centre), and after non-Euclidean movements (right). The former is refined against the spread of pixels (top row), resulting in a reduction of the standard deviation of reciprocal offsets by 0.8% (including outliers), whereas the latter is refined against the centre-point of the reciprocal offsets (bottom row), resulting in a reduction of the mean reciprocal offset by 77.1%.
