SFRD as a function of redshift. The filled red star indicates our measurement. The estimated SFRDs of extrapolated500 μm-risers are shown with empty red-edged triangles: smaller when 250 μm cut is imposed (S₂₅₀ > 13.2 mJy), and larger if all flux cuts are removed. Flux corrections are annotated with arrows. We show for comparison results from other 500 μm-riser selections: B17 (cyan), Dowell et al. (2014; black) and Duivenvoorden et al. (2018; blue). Horizontal bars reflect the bin size. FIR and total FIR+UV observed SFRD (Bourne et al. 2017), as well as total simulated SFRD (B17), are marked with diamonds.
