Spatial distribution of galaxies of various types with the following symbols: red hexagones for ellipticals, purple squares for early-type spirals, green triangles for intermediate spirals, and blue diamonds for late-type spirals. The spectral types of these galaxies were determined in the photo-z computation process fixing the redshifts to their spectroscopic values. The black open symbols (squares, triangles and circles) show the three main dynamically distinct groups. Contours correspond to the XMM-Newton X-ray emission. The black line indicates the direction of the very large scale filament of galaxies found by Boué et al. (2008).
