Cumulative mass fraction integrated over the whole range of masses of k_lum (left, dashed line), k_mass (middle, solid line) and k_1, 2 (right, dotted line). Upward triangles show below main-sequence galaxies while the downward triangles refer to main-sequence galaxies. The three panels on the top row refer to the whole sample while the middle row differentiates between galaxies with M_⋆ > 10¹¹ M_⊙ in red and galaxies with M_⋆ < 10¹¹ M_⊙ in blue. The panel in the bottom row illustrates the difference between main-sequence and below main-sequence galaxies (i.e. Δ_k) for the whole sample as a function of k.
