Fig. 2
Perseus cluster. Top left: reprocessed MSSS map with resolution 20.8′′ × 20.8′′ and rms noise 20 mJy/beam. The contours start at 5σ level and are drawn at 100 mJy/beam × [1, 1.4, 2, 2.8, 4, 5.7, 8, 11, 16, 22, 32, 45, 64, 91, 128]. Top right: Chandra X-ray surface brightness residual map. The image is produced by unsharp masking using archival data in the 0.5–7 keV band with total exposure of 1.4 Ms after standard filtering. Contours correspond to the MSSS image. Bottom: TGSS map with resolution 25.0′′ × 25.0′′ and rms noise 10 mJy/beam. The contours start at 5σ level and are drawn at 50 mJy/beam × [1, 1.4, 2, 2.8, 4, 5.7, 8, 11, 16, 22, 32, 45, 64, 91, 128, 182, 256].
