Spatial distribution of galaxies for each of the morphologies – ellipticals (top), lenticulars (middle), and spirals (bottom) – from the primary spectroscopic sample. Each panel shows the overall density contours for the distribution of each morphology type, split into red and blue galaxies according to the selection criteria discussed in Sect. 4. The faint markers indicate galaxies beyond 0.9 R₂₀₀, which have been excluded from the quantitative analysis presented in this paper. As in Fig. 2, we show the BCG (open green square), system centre (white star), X-ray peak (white plus sign), and approximate location of radio relics (orange crosses).
