Top left panel: total intensity radio contours at 1.2 GHz (VLA in C configuration) with an FWHM of 20 × 20. The contour levels are drawn at  − 3.3 × 10^-4 Jy/beam, 3.3 × 10^-4 Jy/beam, and the rest are spaced by a factor . The sensitivity (1σ) is 1.1 × 10^-4 Jy/beam. Bottom left, right panels: total intensity radio contours at 1.4 GHz (VLA in A configuration) with an FWHM of 2 × 2. The first contour level is drawn at 13.5 × 10^-5 Jy/beam, and the rest are spaced by a factor 2. The sensitivity (1σ) is 4.5 × 10^-5 Jy/beam. The contours of the radio intensity are overlaid on the red plate of the Sloan Digital Sky Survey.
