Spatial distribution and projected phase-space diagram of the spectroscopic members. Top panels: 2D spatial distribution of the 960 spectroscopic member galaxies, classified according to their spectral properties. The circle has a radius equal to r₂₀₀ = 2.63 Mpc. Bottom panels: phase-space diagram of the spectroscopic members, according to their spectral types. The underlying greyscale image in the top and bottom panels shows the galaxy number density distribution in 2D and in the phase-space, respectively, considering the whole population.
