Comparison between the luminosity functions produced by various models at z = 6. The solid red lines and the dashed orange lines represent the SIDES luminosity function using the DL14 or the L18 relation, respectively. The long-dashed brown line is the high SFRD version of SIDES. The models shown for comparison are Lagache et al. (2018, two-dot-dashed turquoise line), Yang et al. (2022, dotted blue line), Yue & Ferrara (2019, short-dash-long-dashed purple line), and Chung et al. (2020, dot-dashed green line).
