RGB and X-ray images of the A3266 cluster. Top panel: RGB image of A3266. The bands used are 0.2–0.5 keV (R), 0.5–1.0 keV (G), and 1.0–2.0 keV (B). We applied a σ = 1 Gaussian smoothing to the exposure-corrected and background-subtracted image. Bottom panel: Exposure-corrected and background-subtracted X-ray surface brightness of the A3266 cluster in the 0.5–9.25 keV energy range. The point-like sources were excluded in the analysis. The 10-level contours of the X-ray image are shown in white.
