Greyscale: SDSS r-band image of the A1430 field with galaxies encircled having a spectroscopic redshift close to the cluster redshift. The main cluster component and the subcomponent are, on average, separated in redshift. The colours mark different redshift intervals corresponding to the discussion in Sect. 4.4: 0.338−0.341 (green), 0.341−0.347 (blue), 0.347−0.348 (magenta), 0.348−0.352 (red), and 0.352−0.358 (orange). Pale red contours represent the distribution of X-ray emission as seen by Chandra to indicate the cluster position.
