Fig. 6


1D and 2D UV VLT/VIMOS MR spectra. The transparent blue stripes indicate the positions of the emission sky lines. The transparent red stripes indicate the telluric molecular sky absorptions bands, B- and A-bands at ~6900 Å and ~7600 Å. In the same panel, three 2D spectra are shown, the reduced, rms and signal-to-noise ratio, from bottom to top. The inset on the left side shows the double-peaked Lya line (from V15). In the bottom right a zoom-in around the He iiλ1640 and O iii]λ1666 positions is shown. Their detections remain tentative. In the bottom left, the 1D spectrum shows the relative Lyα flux in comparison with other lines.
