cds-question@unistra.frquasarsredshiftedline-intensitiesTo study the nature of low-z Ly{alpha} absorbers in the spectra of QSOs, we have obtained high signal-to-noise ratio (S/N) UV spectra of H1821+643 (z_em_=0.297) and PG 1116+215 (z_em_=0.177) with the Goddard High-Resolution Spectrograph on the Hubble Space Telescope.1998ApJ...508..200Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/508/200CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/508/200https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/508/200http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/508/200https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/508/200https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/508/200http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/508/200GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/508/200/table1 (Redshifts of galaxies in the field of H1821+643)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/508/200/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/508/200/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/508/200/table1?GETtext/xml+votable180.050000true274.301458364.56555560.005555555555555556Cone search capability for table J/ApJ/508/200/table2 (Redshifts of galaxies in the field of PG 1116+215)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/508/200/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/508/200/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/508/200/table2?GETtext/xml+votable180.050000true170.191916721.18755560.0055555555555555566/15350 15351 15356 15357 16034 16040 28267 28270 28353 28355 28356 28358https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/508/200?format=asciiOpticaldefaultJ/ApJ/508/200/table1Redshifts of galaxies in the field of H1821+643recnoRecord number assigned by the VizieR team.
