LOFAR radio contours overlaid on the XMM-Newton color image. Left: low-resolution (60″ × 60″) contours spaced by a factor of 2 starting from 1.5σ (the first contour is reported in gray), where σ = 300 μJy beam⁻¹. The negative −1.5σ contours are shown as dashed gray lines. Right: very low-resolution (90″ × 90″) contours spaced by a factor of 2 starting from 3σ, where σ = 415 μJy beam⁻¹. The negative −3σ contours are shown as dashed lines. The beams are displayed in the bottom left corners.
