Left: X-ray surface distribution as obtained from XMM-Newton in the band 0.7−1.2 keV, smoothed with a Gaussian with a width of 12″. The two subcomponents of A1430 are clearly visible. Annuli and sectors show the regions used for spectral extraction and analysis, while barred circles indicate the point sources excluded from the analysis. The labels ‘A’ and ‘B’ denote the main component and the subcomponent of the cluster, respectively. Right: temperature distribution in the cluster. Filled black circles show the temperature profile of the main cluster, measured in the black and white marked regions in the left panel which exclude the interaction with the subcomponent. The magenta and cyan regions show the temperature in the sectors marked with the same colours in the left panel, while the red empty circle represents the temperature of subcomponent A.
