Bolometric (0.1–10 keV) X-ray flux (in units of counts s⁻¹ cm⁻²) of a relaxed cluster (D17–a, left column) and a perturbed one (D12–a, right column). The size of each map is 1R₂₀₀ per side. In the first row, all the particles are considered; in the second and third rows, the volume cut has been applied, considering the 99 per cent and 95 per cent thresholds, respectively.
