cds-question@unistra.frquasarsredshiftedspectroscopyWe present the results of a survey of damped (DLA, logN(HI)>20.3) and sub-damped Lyman-{alpha} systems (19.5<logN(HI)<20.3) at z>2.55 along the lines-of-sight to 77 quasars with emission redshifts in the range 4<z_em_<6.3. Intermediate resolution (R~4300) spectra were obtained with the Echellette Spectrograph and Imager (ESI) mounted on the Keck telescope. A total of 100 systems with logN(HI)>19.5 were detected of which 40 systems are damped Lyman-{alpha} systems for an absorption length of {Delta}X= 378. About half of the lines of sight of this homogeneous survey have never been investigated for DLAs.2009A&A...508..133Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/508/133CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/346/1103 : Redshifts of damped Lyman{alpha} absorbers (Peroux+, 2003)J/ApJ/635/123 : The SDSS-DR3 damped Ly{alpha} survey (Prochaska+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/508/133https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/508/133http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/508/133https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/508/133https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/508/133http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/508/133GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/508/133/table1 (Summary of observations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/508/133/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/508/133/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/508/133/table1?GETtext/xml+votable180.050000true1.9112524.2902780.0055555555555555566/514 522 592 2247 4955 5306 5331 5369 5425 5549 5563 5906 6129 6552 6579 6604 6647 7224 7456 7459 7464 8530 8556 9046 9095 9121 9138 9469 9479 9523 9621 9742 9909 10140 10193 10393 10473 10571 10643 10649 10692 10734 10753 10759 11078 11319 11461 11468 11489 11636 12035 12563 12622 13342 15278 17662 17746 17812-17813 17895 18200 18208-18209 18227 18262 18414 18943 19087 19154 19309 19411 19490 19928 20073 20249 20327 20384 22975 23191 23225 26165 26189 26280-26281 26427 26568 26846 27041 27161-27162 27225 27511 27738 27855 31706 32466 36792https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/508/133?format=asciiOpticaldefaultJ/A+A/508/133/table1Summary of observationst.expExposure timemintime.duration;obs.exposureintQSOQSO namemeta.id;meta.maincharprimaryrecnoRecord number assigned by the VizieR team.
