Left: X-ray emission from ROSAT. The image from the ROSAT All Sky Survey was smoothed with a 200′′ FWHM Gaussian and is shown in orange colors. Solid contours are from the WSRT L-band image and drawn at levels of  [1,2,4,8,...]  × 0.15 mJy beam^-1. Right: WSRT L-band image (1160–1780 MHz) with sources labelled. Contour levels are drawn at  [1,2,4,8,...]  × 80 μJy beam^-1. The beam size is 29″ × 19″ and indicated in the bottom left corner of the image.
