Spatial distribution of the HαIR sample, classified according to spatial distribution as well as redshift (subgroups 1–8) in section 4.5. The colorbar represents redshift: redder markers are more redshifted than bluer ones. The two dashed circles represent the virial radius, and the distance of 0.6r₂₀₀. We expect an overdensity of galaxies around the latter, given the higher number of galaxies that we can see in this region in Fig. 5.
