Caption: Figure 3.

Σ_SFR distributions for SDSS and MOSDEF galaxies. The black histogram indicates the distribution in Σ_SFR for the z ∼ 0 SDSS sample, while the shaded green [blue] histogram indicates the corresponding distribution for z ∼ 2.3 [z ∼ 1.5] MOSDEF galaxies. Equation (2) is used to translate the median Σ_SFR of each distribution to a corresponding f_DIG. While local star-forming galaxies typically have f_DIG = 0.54, the median Σ_SFR of z ∼ 2.3 MOSDEF galaxies, which is almost two orders of magnitude higher, suggests f_DIG = 0.
