Inferred luminosity functions derived for the elliptical (top) and the spiral (bottom) populations using the 68% confidence intervals (blue). Our results are compared with the results of López-Sanjuan et al. (2017) in green, Brown et al. (2007) in pink, Beare et al. (2015) in red, Salimbeni et al. (2008) in brown, Drory et al. (2009) in purple, and Faber et al. (2007) in orange. Our g′ magnitudes are converted into the Johnson B-band absolute magnitude, at redshift z = 0.5 and for H₀ = 100 km s⁻¹ Mpc⁻¹ using B − g′ = 0.78 for ellipticals and B − g′ = 0.40 for spirals, listed in Table 7 of Fukugita et al. (1995).
