cds-question@unistra.frsurveysgalaxiesphotometryultraviolet-astronomyWe combine data from the extremely deep Hubble Space Telescope U (F300W) image, obtained using WFPC2 as part of the parallel observations of the Hubble Ultra Deep Field campaign, with BVi images from the Great Observatories Origins Deep Survey to identify a sample of Lyman break galaxies in the redshift range 2.0<=z<=3.5. We use recent stellar population synthesis models with a wide variety of ages, metallicities, redshifts, and dust content, and a detailed representation of the HI cosmic opacity as a function of redshift to model the colors of galaxies in our combination of WFPC2 and ACS filters. Using these models, we derive improved color selection criteria that provide a clean selection of relatively unobscured star-forming galaxies in this redshift range. Our WFPC2 F300W image is the deepest image ever obtained at that wavelength. The 10 limiting magnitude measured over 0.2arcsec^2^ is 27.5mag in the WFPC2 F300W image, about 0.5mag deeper than the F300W image in the Hubble Deep Field (HDF)-North.2006AJ....132.1023Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/132/1023CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/653/53 : z~6 galaxies UV luminosity function (Bouwens+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/132/1023https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/132/1023http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/132/1023https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/132/1023https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/132/1023http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/132/1023GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/132/1023/table2 (U band dropouts)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/132/1023/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/132/1023/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/132/1023/table2?GETtext/xml+votable180.050000true53.13704806-27.712828890.0055555555555555566/35935https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/132/1023?format=asciiUVOpticaldefaultJ/AJ/132/1023/table2U band dropoutsrecnoRecord number assigned by the VizieR team.
