Example of how bending angle and size are measured. The black ‘+’ shows the location of the optical counterpart, and the white ‘+’ shows the location of the highest radio intensities in the lobes. The white lines connect the location with the optical counterparts with the highest intensities, which are used to calculate the bending angle θ. The dashed lines show the fitted box around the edges of the 3σ contours used to calculate the size of the source.
