Rest-frame spectra of the galaxies in the C3-VANDELS subsample. From the left to right panels, we highlight the following emission lines (which are marked with the dashed black line): Lyα, CIVλλ1548,51, HeIIλ1640, OIII]λλ1661,66, CIII]λλ1907,09, [OII]λλ3727,3729, Hβ, [OIII]λλ4959,5007, and Hα. The flux density is in arbitrary units. Each galaxy is shown with the same color in each panel, and its ID is plotted in the [OIII]λλ4959,5007 panel.
