X-ray luminosity vs. velocity dispersion with large scale structure density cut at D₁₀ = 5. Black circles show the compact and blue circles show the extended X-ray source samples, with D₁₀ > 5. with their scaling relations as dotted lines. Red and cyan circles show respectively the compact and extended samples having D₁₀ ≤ 5. with scaling relations as dashed lines. Other details are the same as in Fig. 3.
