Cumulative and local SFE profiles of model clusters with different stellar density profiles corresponding to the Dehnen model (γ = 0, 1, 2 in red, green, and blue solid lines) and the Plummer model (dashed lines), given in thick and thin lines, respectively. SFE per free-fall time of ϵ_ff = 0.05 and the SF duration of t_SF = 1 Myr (or equivalently ϵ_ff = 0.01 and t_SF = 5 Myr) were adopted to recover the density profiles of the residual gas for a cluster with M_⋆ = 6000ℳ_⊙ and r_h = 1.23 pc. The vertical lines correspond to the stellar half-mass radius, r_h (black solid line), 10a_D (red, green, and blue solid lines corresponding to γ = 0, 1 and 2), 10a_P (black dashed line), and the Jacobi radius, R_J (black dotted line), respectively.
