Median density radial profiles of clumps of radius between 2 × 10⁷ M_⊙ and 3 × 10⁷ M_⊙, grouped in three bins of excess mass Δ_M. The numbers in square brackets indicate the slope of each curve measured in log–log space in the inner 100 pc. (The conclusions do not change when considering larger radial ranges.) Higher excess masses correspond to more centrally concentrated clumps (steeper profiles).
