Mass function slopes for all (individual) stars with mass ≥ 2 M_⊙. Red filled circles are the present-day mass functions for the ejected stars (α_ej). Blue stars are the averaged present-day mass function slopes of the stars that remain in the clusters at 3 Myr (⟨ α_in ⟩), while black open triangles are those at 0 Myr (i.e. IMF, ⟨ α_i ⟩). The canonical value of the upper IMF, α₂ = 2.3 (Eq. (1)), is indicated with a dotted grey line.
