Notes. The listed parameters include the redshift (z), velocity dispersion (σv), the total stellar mass formed at the time of observation (
), metallicity (Z), the logarithmic SFR ratio between adjacent time bins (Δlog(SFR)i, where i = 1, …, 6 labels the time bins) ionization parameter (log U), the V-band attenuation (AV), and the dust attenuation model parameters (c1 − c4). zsp = 6.5676 is the spectroscopic redshift of the source from DAWN (Brammer 2022, 2023b).
