Scientific paper

The core of our sample is formed by the high-resolution, high S/N QSO spectra already described in Saitta et al. (2008MNRAS.385..519S) and D'Odorico et al. (2008MNRAS.389.1727D). Most of them were obtained with the Ultraviolet and Visual Echelle Spectrograph (UVES) spectrograph at the Kueyen unit of the European Southern Observatory (ESO) VLT (Cerro Paranal, Chile) in the framework of the ESO Large Programme (LP): 'The Cosmic Evolution of the IGM' (Bergeron et al., 2004Msngr.118...40B).
In this work, three more QSOs were added to that sample, mainly to increase the redshift extension above z~3. UVES spectra of the QSOs, Q0055-269, PKS 2000-330 and PKS 1937-101, were downloaded from the ESO Archive and reduced with the UVES pipeline following the standard procedure. The continuum level was determined by interpolating with a cubic spline of the region of the spectrum free from evident absorption features.
