cds-question@unistra.frgalaxy-clustersredshiftedhst-photometryWe present results of the HST Advanced Camera for Surveys spectroscopic ground-based redshift survey in the field of A1689. We measure 98 redshifts, increasing the number of spectroscopically confirmed objects sixfold. We present two spectra from this catalog of the Sextet Arcs, images that arise from a strongly lensed Lyman break galaxy (LBG) at a redshift of z=3.038. Gravitational lensing by the cluster magnifies its flux by a factor of ~16 and produces six separate images with a total r-band magnitude of r_625_=21.7. The two spectra, each of which represents emission from different regions of the LBG, show HI and interstellar metal absorption lines at the systemic redshift.2007ApJ...665..921Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/665/921CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/382/60 : BVR photometry in Abell 1689 (Duc+, 2002)J/MNRAS/335/10 : H{alpha} survey of Abell 1689 (Balogh+, 2002)J/ApJ/621/53 : Multiple arc systems in A1689 (Broadhurst+, 2005)J/MNRAS/372/1425 : Abell 1689 gravitational lensing analysis (Halkola+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/665/921https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/665/921http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/665/921https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/665/921https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/665/921http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/665/921GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/665/921/table1 (Objects at z>2.5 in the A1689 Field)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/665/921/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/665/921/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/665/921/table1?GETtext/xml+votable180.050000true197.86020833-1.332430560.005555555555555556Cone search capability for table J/ApJ/665/921/table3 (Spectroscopic identification of z<2.5 objects toward A1689)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/665/921/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/665/921/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/665/921/table3?GETtext/xml+votable180.050000true197.83037083-1.328727780.0055555555555555566/26189https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/665/921?format=asciiOpticaldefaultJ/ApJ/665/921/table1Objects at z>2.5 in the A1689 FieldrecnoRecord number assigned by the VizieR team.
