cds-question@unistra.frgalaxiescatalogsphotometryredshiftedWe present the basic data for a large ground-based spectroscopic survey for z~3 Lyman break galaxies (LBGs), photometrically selected using rest-UV colors from very deep images in 17 high Galactic latitude fields. The total survey covers an area of 0.38deg^2^ and includes 2347 photometrically selected candidate LBGs to an apparent {R}_AB_ magnitude limit of 25.5. Approximately half of these objects have been observed spectroscopically using the Keck telescopes, yielding 940 redshifts with <z>=2.96+/-0.29. We discuss the images, photometry, target selection, and spectroscopic program in some detail and present catalogs of the photometric and spectroscopic data, made available in electronic form. We discuss the general utility of conducting nearly volume-limited redshift surveys in prescribed redshift intervals using judicious application of photometric preselection.2003ApJ...592..728Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/592/728CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/519/1 : Lyman-break galaxies at z>~4 (Steidel+, 1999)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/592/728https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/592/728http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/592/728https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/592/728https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/592/728http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/592/728GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/592/728/table1 (Deep Imaging Observations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/592/728/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/592/728/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/592/728/table1?GETtext/xml+votable180.050000true0.8542083-26.06022220.005555555555555556Cone search capability for table J/ApJ/592/728/lbg (Lyman break galaxies (tables 7 to 23 of paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/592/728/lbg?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/592/728/lbg?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/592/728/lbg?GETtext/xml+votable180.050000true0.821375-26.10088890.0055555555555555566/0 4946 4947 5063 5069 8644 8912 8914 11252 11424 11425 16589 17749 18271 19033 19036 19311 19397 19416 19717 19719 19728 23208 23210https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/592/728?format=asciidefaultJ/ApJ/592/728/table1Deep Imaging ObservationsrecnoRecord number assigned by the VizieR team.
