cds-question@unistra.frquasarsspectroscopyastrometryapparent-magnituderedshiftedline-intensitiesWe present the spectroscopic observations of 56 quasars that were discovered by AQD (Automated Quasar Detection) in a field of ~25.3deg2, centred at (1950) RA l0h40m00s, Dec. 05deg00'00". These observations, with the CTIO 4-m telescope, led to the discovery by Clowes & Campusano of a large group of quasars with size ~100-200h^-1^Mpc at z~1.3. Quasars of particular interest are noted, including one that is a BAL quasar with z~1.78.1994MNRAS.266..317Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/266/317CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/266/317https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/266/317http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/266/317https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/266/317https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/266/317http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/266/317GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/266/317/table1 (A summary of the observations of the 56 candidates that were confirmed as quasars.)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/266/317/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/266/317/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/266/317/table1?GETtext/xml+votable180.050000true158.4092142.5433890.0055555555555555565/6853 6/27065-27069 27071 27398-27399 27405 27408 27410-27411 27417 27420 27422-27423 27441 27444 27446 27458-27459 27464-27465https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/266/317?format=asciiOpticaldefaultJ/MNRAS/266/317/table1A summary of the observations of the 56 candidates that were confirmed as quasars.recnoRecord number assigned by the VizieR team.
