Spatial distribution of all galaxies with redshift in the MACS0329 field. The large black circle indicates the R₂₀₀ radius of the cluster. Red triangles and dots show galaxies with TNG and CLASH-VLT redshifts, 18 and 1712, respectively. The symbols outlined with blue circles indicate the 41 group member galaxies. The point 0,0 in the diagram indicates the center of GrG J0330−0218 and the green circle indicates the 0.5 R₂₀₀ radius of the group (see also Fig. 1).
