Six examples of the noisy mock JWST/NIRSpec spectra, for six different effective temperatures at various redshifts. Each figure includes the spectra for both a peak magnitude of 26 (in black) and 27 (in blue) AB mag, where the 27 mag spectrum is shifted down by 50 nJy to avoid cluttering. The metal absorption lines included in Table 1, as well as hydrogen lines, are marked in red, indicating features detectable at 26 AB mag. The green regions mark broader features, within which at least one of the contributing lines has been identified. In all figures, except one, detectable spectral lines appear. The exception, with T_eff = 15 000 K and z = 3, instead gives an example of a spectrum with no detections. The general conclusion from these figures is that stars with higher effective temperatures at higher redshifts result in a larger number of detectable metal lines, while cooler stars instead contribute with many hydrogen Balmer lines.
