Posterior distributions of the LF parameters α, ${\stackrel{\sim }{L}}^{★}$, and log(Φ^★) inferred from the Bayesian model for the overall sample (dark blue) and for two redshift bins: 3 < z < 4 (light blue) and 4 < z < 5 (purple). Rightmost panels: Marginalized one-dimensional posterior distributions for each parameter. Other panels: Joint two-dimensional posterior distributions, highlighting the correlations between parameters. The 5th, 50th, and 95th percentiles are shown.
