Various X-ray properties of cluster A980. Panel a: Chandra X-ray map in gray and black contours, over-plotted with the GMRT 325 MHz (low-resolution) contours (green). The sectors (10° −100° (CF1) and 175°–243°(CF2)) along which sources B and A are extended, respectively, are marked as red cones. Blue boxes denote the pre- and post-cold-front regions (T₂ and T₁, respectively) (see text). Panel b: azimuthally averaged X-ray surface brightness (SB) profile, with the best-fit double β-model. The individual β-models are shown with dotted lines and the residuals are shown in the bottom panel. Panel c: SB profiles for the two conal sectors and the fitted broken power-law models are shown with red and blue curves, respectively.
