Left: colorscale: X-ray surface brightness at 0.5−7 keV in linear scale smoothed with a 2D Gaussian of σ = 3′′. The observation was taken with the Chandra ACIS-I. The cluster components are labeled with “A” and “B”. Black contours: WSRT 346 MHz image after subtracting compact sources. The noise level is σ_rms ≈ 1.0 mJy/beam. Contour levels are drawn at [− 3.0, 3.0, 4.2 , 6.0, 8.5, 12.0] mJy. The negative contour is drawn with a dashed line. Blue dashed line: region where the radio flux density related to the main cluster component A was measured. The skymodel for subtraction is based on the measured flux densities in the GMRT image at 322 MHz, listed in Table 1. The shape of the restoring beam is 182′′ × 91′′ with a position angle of 0°. Right: image obtained using a more aggressive subtraction procedure. The shape of the restoring beam is 170′′ × 85′′ with a position angle of 0°.
