LF obtained from the combination of the four MUSE surveys considered in this study (see Table 1). Top panel: Median LF reconstructed using our Bayesian model applied to the full sample (solid black line), along with the corresponding 90% credible interval. The blue colour-coded diamonds represent the 1/V_max estimates from each individual survey, with vertical bars indicating the Poisson uncertainties and horizontal bars the bin widths. The dark blue circles show the weighted average of the 1/V_max points across surveys in each bin. Arrows in the same colour scheme indicate the luminosity limit above which each survey reaches a completeness higher than 10%. For comparison, coloured lines with different line styles display the best-fit Schechter LFs from various studies in the literature (Herenz et al. 2019; Thai et al. 2023). Bottom panel: Statistical uncertainty on the LF as a function of luminosity. The solid black lines show the relative 5th and 95th percentiles of the Bayesian posterior distribution.
