cds-question@unistra.frquasarsredshiftedphotometryWe present data for over 100 high-redshift quasars found in ~700deg^2^ by the Sloan Digital Sky Survey (SDSS), using automated selection algorithms applied to SDSS imaging data and with spectroscopic confirmation obtained during routine spectroscopic observations by the Sloan 2.5 m telescope. The SDSS spectra cover the wavelength range 3900-9200{AA}E at a spectral resolution of 1800 and have been obtained for 116 quasars with redshifts greater than 3.94; 92 of these objects were previously uncatalogued, significantly increasing the current list of published z>4 quasars. The paper also reports observations of seven additional new z>4 quasars; all were selected from the SDSS imaging survey and spectroscopically confirmed with observations by the Apache Point Observatory's 3.5 m telescope or the Hobby-Eberly Telescope.2001AJ....122..503Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/122/503CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/123/377 : u*g*r*i*z* Photometry of stars, galaxies, QSOs (Newberg+ 1999)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/122/503https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/122/503http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/122/503https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/122/503https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/122/503http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/122/503GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/122/503/table1 (Positions and photometry of SDSS high-redshift quasars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/122/503/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/122/503/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/122/503/table1?GETtext/xml+votable180.050000true4.9585417-0.6780.005555555555555556Cone search capability for table J/AJ/122/503/table2 (Radio-detected quasars in sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/122/503/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/122/503/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/122/503/table2?GETtext/xml+votable180.050000true7.861666715.12766670.0055555555555555566/0 522 554 4106 6385 6552 6559 6576 6580-6581 6595 6604 6613 6629 7230 7274 7288 7293 7301 7308-7309 7311 7316 7367 7378 7459 7464-7465 7470 7478-7479 7482 7522 7526 7569 10092 10177 10193 10212-10214 11597 11952 17746 17751 17812 17818 18006 18022 18024 18032 18062 18065 18295 18389 18403 18778 19030 19033 19046 19458 19756-19757 21843 21847 23043 23047 23049 23072 23075 23185 23191-23192 25848 25919 25938 25969 25999 26005 26023 26189 26204 26209 26211 26215 26943 26990 26992 27023 27025 27031 27035 27038 27043-27044 27074 27222 27225 27304 27306 31310 31318 31373 31409 36725 36734 36765-36766 36785 36792 36802 36810 36816https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/122/503?format=asciiOpticaldefaultJ/AJ/122/503/table1Positions and photometry of SDSS high-redshift quasarszRedshiftsrc.redshiftfloatrecnoRecord number assigned by the VizieR team.
