Notes.
The fluxes and upper limits were calculated by integrating the spectra in the velocity range of −250 < v [km s−1] < 300 and taking a redshift of 10.602 as a reference.
The definitions for the line ratios are given in Sect. 3.3.
The log(U) was computed using the O32 ratio and the calibration presented in Berg et al. (2019) for 0.1 Z⊙.
The SFR was derived considering the Hα luminosity and 0.1 Z⊙ (Theios et al. 2019).
The sSFR was derived from the Hα SFR and the mean of stellar masses from the SED fitting of the NIRSpec spectrum (Bunker et al. 2023) and NIRCam photometry (Tacchella et al. 2023).
