The orange region shows the 68% contour luminosity density results as a function of redshift for three wavelengths (labeled on the plots) for our physically based model here. The violet shaded region is the 68% contour result from J. D. Finke et al. (2022) Model B. The blue curve is the model from J. D. Finke et al. (2010), and the symbols show the measurements from A. Saldana-Lopez et al. (2021, red squares), L. Tresse et al. (2007, blue triangles), and other sources (black circles) described in J. D. Finke et al. (2022).
