Stellar-to-dynamical mass ratio as a function of compactness under different assumptions. In all panels, points are colour-coded by DoR, while grey symbols indicate non-corrected masses, with arrows marking correction-driven shifts. Top: IMF-corrected stellar masses with a constant virial coefficient K = 5. Middle: Structure-dependent virial coefficient K = K_PdA with Kroupa stellar masses. Bottom: Fully adjusted configuration combining K = K_PdA with IMF-corrected stellar masses.
