2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/12995We report on high resolution observations (R=35000) of the Hubble Deep Field South QSO J2233-606 obtained with the University College London Echelle Spectrograph at the AAT. We present spectral data and an associated absorption line list for the wavelength region 3530 < lambda < 4390A. The data has a mean signal-to-noise ratio in the continuum of approximately 15 per 0.05A resolution element at lambda > 3700A.8 pages LaTeX, including 1 figure, submitted to MNRASAstrophysicstext
