cds-question@unistra.frquasarsredshiftedphotometryThis paper describes the acquisition and analysis of imaging data for the identification of galaxies associated with z~4 damped Ly{alpha} systems. We present deep BRI images of three fields known to contain four z~4 damped systems. We discuss the reduction and calibration of the data, detail the color criteria used to identify z~4 galaxies, and present a photometric redshift analysis to complement the color selection. We have found no galaxy candidates closer to the QSO than 7" that could be responsible for the damped Ly{alpha} systems. Assuming that at least one of the galaxies is not directly beneath the QSO, we set an upper limit on this damped Ly {alpha} system of L<L^*^_LBG_/4. Finally, we have established a Web site to release these imaging data to the public, at http://kingpin.ucsd.edu/~dlaimg/papers/refern.html . The observations where made with LRIS on the Keck II telescope, on 13 Jan 1999 for PSS 0132+1341 and BR 0951-0450, and 23 Jan 1999 for PSS 1443+2724.2002AJ....123.2206Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/123/2206CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tohttp://kingpin.ucsd.edu/~dlaimg/papers/refern.html : reduced imageshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/123/2206https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/123/2206http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/123/2206https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/123/2206https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/123/2206http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/123/2206GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/123/2206/table4 (Photometry for PSS J0132+1341)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/123/2206/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/123/2206/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/123/2206/table4?GETtext/xml+votable180.050000true22.9956811113.658176940.005555555555555556Cone search capability for table J/AJ/123/2206/table5 (Photometry for BR 0951-0450)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/123/2206/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/123/2206/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/123/2206/table5?GETtext/xml+votable180.050000true148.44409889-5.1199550.005555555555555556Cone search capability for table J/AJ/123/2206/table6 (Photometry for PSS J1443+2724)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/123/2206/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/123/2206/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/123/2206/table6?GETtext/xml+votable180.050000true220.8415911127.405998060.0055555555555555566/9093 9095 18381 18383 27161https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/123/2206?format=asciiOpticaldefaultJ/AJ/123/2206/table4Photometry for PSS J0132+1341recnoRecord number assigned by the VizieR team.
