Bending angle in degrees of radio sources in X-ray galaxy groups as a function of distance to the group centre in units of r₂₀₀ for the XMM-LSS field. We distinguish between the core region (0 < r/r₂₀₀ < 0.1) and the inner region (0.1 < r/r₂₀₀ < 1) of the groups. The black lines and error bars show the median and standard median error of the BAs in the regions. The redshift of the radio sources is shown with a colour bar. The dashed line at 180° indicates a straight source.
