Notes. For each source, we provide the physical parameters derived for each of the redshift intervals considered in this work, corrected for lensing magnification (μ = 1.26). We distinguish between the results obtained from the PSF/aperture photometry with Dense Basis (stellar fit; Sect. 4.1) and Bagpipes (stellar fit + AGN; Sect. 4.2), and those obtained for the stellar component with Dense Basis (Sect. 4.3), obtained by subtracting the Bagpipes AGN photometric points from the LRD PSF photometry. Upper and lower bounds of each value (which corresponds to the median) indicate the 16th and 84th percentiles. For some values of the Dense basis (stellar fit) of LRD1, both percentiles are identical to the median value, highlighting that only a few models can fit this galaxy using only stars. Coordinates are not corrected for lensing magnification (check Table A.1 for the corrected positions).
