Comparison with model predictions. Red crosses show our reconstructed LF points in the redshift range of 5.0 < z < 6.7. Two additional crosses in the bright end, having log(L)[erg s⁻¹] > 43, are taken from the literature, obtained the same way as described in Sect. 5.2. Black and blue solid lines show predictions from the AMIGA models with single- and double-ionization scenarios, respectively. Predicted LFs from the SPHINX simulation (Garel et al. 2021) are shown as dashed lines: intrinsic LF (magenta), attenuation by dust (green), and by IGM (orange).
