LUQAS at Cambridge

LUQAS (Large sample of UVES QSO Absorption Spectra) consists of 27 high resolution, high signal-to-noise spectra taken with the Ultra-Violet Echelle Spectrograph (UVES) on VLT (Paranal, Chile) over the period 1999-2002. The spectra were taken from the ESO archive and are publicly available to the ESO community. The total redshift path of the sample is Delta z = 13.7. The median redshift of the sample is z=2.25. The sample and the reduction of the spectra is described in more detail in the first paper below.
