Spatial distribution of the 89, 124, and 89 member galaxies of GrG1, GrG2, and GrG3 shown with small circles (black, green, and red as in Fig. 17). The corresponding R₂₀₀ radii are represented by large black, green, and red circles. Small blue dots and the large blue circle indicate 430 members and the R₂₀₀ radius of MACS0329. The black dashed circle refers to the western galaxy concentration of GrG1 (see text). Galaxies belonging to the secondary peak GrG2bis are very sparse in the field, as shown by blue crosses. The plot is centered on the BCG of MACS0329.
