ρ_CS(z) for four flux threshold cases of −11.85, −11.62, −11.4, and −11.3. The filled circles indicate the LGRB-RD corrected for intrinsic luminosity evolution for the CS. The filled circles are color-coded with respect to the vertical dashed lines in the right panel of Figure 7. The black dashed lines show the SFRD from the MD14 study. The peak of SFRD is renormalized to the peak of LGRB-RD for easier comparison.
