Extended Data Fig. 4

The two horizontal yellow lines in the 2D spectra indicate the extraction aperture used to measure the 1D spectra. Dotted purple vertical lines indicate the ___location of several emission lines when present. The shaded grey area corresponds to 1σ uncertainties in the 1D spectra and the zero flux level is marked by a dashed black horizontal line.
