Fig. 4

Final normalized spectrum from 3850 to 25 200 Å. The apparent features just redward of 4000 Å and blueward of 10 000 Å are at the edge of the optical grism range where the response is not reliable. The high levels of noise at ~14 000 Å and ~19 000 Å are artefacts of the telluric correction while the absorption feature at 7625 Å is atmospheric.
