Top: azimuthally averaged brightness of the radio halo at 325 (triangles) and 1400 MHz (circles) versus the distance from the cluster center at a resolution of 60′′. Arrows represent 3σ upper limits. In the inset we show the annuli used to calculate the azimuthally averaged brightness. Masks have been used to exclude discrete sources from the statistics. Bottom: spectral index radial profile.
