cds-question@unistra.frquasarsgalaxiesphotometryinfrared-photometryvisible-astronomybroad-band-photometryWe have imaged a 45'x45' area centered on the Hubble Deep Field (HDF) in UBVRI passbands, down to the limiting magnitudes of approximately 21.5, 22.5, 22.2, 22.2, and 21.2, respectively. The principal goals of the survey are to identify quasi-stellar objects (QSOs) and to map structure traced by luminous galaxies and QSO absorption line systems in a wide volume containing the HDF. The area surveyed is 400 times as large as that of the HDF, and 40 times as large as that of the HDF Flanking Fields. We have selected QSO candidates from color space and identified four QSOs and two narrow emission line galaxies not yet discovered, bringing the total number of known QSOs in the area to 19.2000AJ....119.2571Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/119/2571CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/112/359 : Galaxies in the Hubble Deep Field (van den Bergh+ 1996)J/ApJ/513/34 : HDF photometric redshifts catalog (Fernandez-Soto+, 1999)J/ApJS/127/1 : UGRK photometry in the Hubble Deep field region (Hogg+, 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/119/2571https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/119/2571http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/119/2571https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/119/2571https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/119/2571http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/119/2571GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/119/2571/table2 (Unconfirmed UVX QSO candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/119/2571/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/119/2571/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/119/2571/table2?GETtext/xml+votable180.050000true188.447541762.23605560.005555555555555556Cone search capability for table J/AJ/119/2571/table4 (Unconfirmed high-z QSO candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/119/2571/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/119/2571/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/119/2571/table4?GETtext/xml+votable180.050000true189.795583362.57844440.005555555555555556Cone search capability for table J/AJ/119/2571/table5 (Spectroscopically confirmed QSOs and galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/119/2571/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/119/2571/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/119/2571/table5?GETtext/xml+votable180.050000true188.504333362.55433330.005555555555555556Cone search capability for table J/AJ/119/2571/table6 (Spectroscopically identified stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/119/2571/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/119/2571/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/119/2571/table6?GETtext/xml+votable180.050000true188.599541762.27669440.005555555555555556Cone search capability for table J/AJ/119/2571/phothdf (Photometry and stellarity of objects detected in at least one band)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/119/2571/phothdf?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/119/2571/phothdf?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/119/2571/phothdf?GETtext/xml+votable180.050000true188.391666762.56794440.0055555555555555566/11227 11230-11231 11249 11252https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/119/2571?format=asciiOpticalInfrareddefaultJ/AJ/119/2571/table2Unconfirmed UVX QSO candidatesrecnoRecord number assigned by the VizieR team.
