Velocity offset or radial distance from the mean structure redshift (⟨z⟩ = 2.168; dashed line) as a function of projected distance from the structure center (defined by the coordinates median). Filled circles represent sources in the 3 components described in Sect. 3.4: A in red, B in magenta, and D in blue. The remaining members are shown as open circles (magenta if at 2.15 ≤ z < 2.164, blue if at z > 2.19, and green if at intermediate redshifts, 2.164 < z < 2.19). Spectroscopically identified AGN are annotated, and X-ray selected AGN are marked with black stars.
