Fraction of the combined SFRD recovered by UV (light blue and blue histograms) and IR (red histograms) data as a function of redshift. The filled blue histograms show the fraction recovered by the observed UV (i.e., without dust correction), while the light-blue dashed histograms correspond to the dust-corrected UV. We note that the UV and IR fractions do not sum to unity, since each SFRD is obtained by integrating the respective best-fit SFR function.
