Cumulative MF of star-forming galaxies at t₂ in red (lowest redshift bin) and at t₁ in black (highest redshift bin). The contribution of galaxies quenched between t₁ and t₂ is removed from the cumulative MF at t₁. The dashed lines correspond to the uncertainties. The shifts Δlog ℳ used to estimate the sSFR are shown with the horizontal arrows at four reference masses: ℳ_R = 10¹⁰, 10^10.25, 10^10.5, 10^10.75ℳ_⊙ in blue, green, brown and orange, respectively.
