cds-question@unistra.frsurveysspectroscopyultraviolet-astronomyquasarsvisible-astronomysloan-photometryWe present a set of 71 quasars observed in the near ultraviolet with the PR200L prism on the Advanced Camera for Surveys and the G280 grism on the Wide Field Camera 3 (WFC3) on board the Hubble Space Telescope. The quasars were selected from the Sloan Digital Sky Survey data to search for intervening Lyman limit system (LLS) absorption. The sample was subjected to the constraints that the quasars have AB magnitude g'<18.5, quasar emission redshift 2.3<z_em_<2.6, and lack strong BAL or z~z_em_ absorption. The median emission redshift of the sample is {bar}z=2.403. The data were all processed using custom data reduction pipelines, and the one-dimensional spectra have sufficient signal-to-noise ratio and resolution to easily identify absorption from LLS over the redshift range 1.2<z<2.5. The WFC3 data presented here are the first non-calibration spectra from the G280 grism.2011ApJS..195...16Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/195/16CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/hst : HST Archived Exposures Catalog (STScI, 2007)II/276 : The SDSS Photometric Catalog, Release 5 (Adelman-McCarthy+, 2007)J/ApJ/690/1181 : UV-bright quasars (Syphers+, 2009)J/AJ/137/3761 : Ultraviolet quasi-stellar objects (Bianchi+, 2009)J/AJ/133/1780 : GALEX/SDSS quasar catalog (Trammell+, 2007)http://www.stsci.edu/hst/acs : Advanced Camera for Surveys home pagehttp://www.stsci.edu/hst/wfc3 : Wide Field Camera 3 home pagehttp://cosmo.smcvt.edu/groups/hstacswfc3survey/ : HST ACS+WFC3 Survey pagehttp://www.sdss.org/ : The Sloan Digital Sky Survey home pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/195/16https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/195/16http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/195/16https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/195/16https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/195/16http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/195/16GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/195/16/table1 (Full input sample of HST QSOs)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/195/16/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/195/16/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/195/16/table1?GETtext/xml+votable180.050000true16.7414167-8.91669440.0055555555555555566/4115 4182 4229 4238 4790 4844 5013 5018 5071 5102 5108 5517 5586 5804 6033 6066 6142 6442 6549 6576 6643 7178 7235 7316 7368 7427 7476 7496 7500 8203 9272 9364 9434 9452 9604 9614 9793 9797 9843 9861 9877 9911 9961 10063 10121 10545 10658 10693 10838 10919 10975 10976 11002 11024 11025 11040 11093 11107 11212 11253 11326 11459 11813 11872 11918 11925 11932 12381 17584 17778 18514 18625 19038 19109 19116 19120 20032 22715 23076 25999 26010 26091 26206 26218 26235 26329 26333 26368 26372 26392 27084 27104 27261 27355 27588 27673 27691 28173 491063.588997330618193e-19 4.653515163505597e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/195/16?format=asciiUVOpticaldefaultJ/ApJS/195/16/table1Full input sample of HST QSOsrecnoRecord number assigned by the VizieR team.
