cds-question@unistra.frquasarsspectroscopyredshiftedHigh spectral resolution (FWHM = 0.6 or 0.35 {AA}) were obtained for six high redshift QSOs, z_em_ > 2.2, containing lines from 31 metal-rich absorption line systems amongst which 20 Civ doublets split in subcomponents with velocity differences within a system smaller than 400 km.s^-1^. Our survey has been combined with published data at similar resolution and the resulting sample comprises 35 systems, 23 of which are splitted in a total of 87 subcomponents. The mean redshift of the sample is <z> = 2.65. The observations were carried out at the F/8 Cassegrain focus of the 3.6m telescope at la Silla, between 1984 and 1989.1994A&A...283..759Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/283/759CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/283/759https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/283/759http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/283/759https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/283/759https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/283/759http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/283/759GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/283/759/qso (Positions of the QSOs (from SIMBAD))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/283/759/qso?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/283/759/qso?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/283/759/qso?GETtext/xml+votable180.050000true0.845417-26.0547220.0055555555555555566/16589 17857 21012 25120 34202 34570 35272 36417 48149 48610https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/283/759?format=asciiOpticaldefaultJ/A+A/283/759/qsoPositions of the QSOs (from SIMBAD)recnoRecord number assigned by the VizieR team.
