The KODIAQ survey is aimed at studying galactic and circumgalactic gas in absorption at high redshift, with a focus on highly ionized gas traced by O vi, using the HIRES spectrograph on the KeckI telescope. KODIAQ DR1 consists of a fully reduced sample of 170 quasars at 0.29&lt;z_em_&lt;5.29 observed with HIRES at high resolution (36000{&lt;=}R{&lt;=}103000) between 2004 and 2012. DR1 contains 247 spectra available in continuum normalized form, representing a sum total exposure time of ~1.6 megaseconds. These coadded spectra arise from a total of 567 individual exposures of quasars taken from the Keck Observatory Archive (KOA) in raw form and uniformly processed using a publicly available HIRES data reduction package. DR1 is publicly available to the community, housed as a higher level science product at the KOA. We will provide future data releases that make available additional quasars, including those with pre-2004 observations taken with the previous-generation HIRES detectors.</description><source format="bibcode">2015AJ....150..111O</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/150/111</referenceURL><type>Catalog</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/TAP">TAP VizieR generic service</relatedResource></relationship><relationship><relationshipType>IsServedBy</relationshipType><relatedResource>Conesearch service</relatedResource></relationship><relationship><relationshipType>related-to</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/J/MNRAS/345/609">J/MNRAS/345/609 : Variability of the fine-structure constant (Murphy+, 2003)</relatedResource></relationship></content><rights>https://cds.unistra.fr/vizier-org/licences_vizier.html</rights><capability><interface xsi:type="vr:WebBrowser"><accessURL use="full">https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/150/111</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/150/111</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/150/111</mirrorURL></interface></capability><capability><interface xsi:type="vs:ParamHTTP"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/150/111</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/150/111</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/150/111</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface></capability><capability standardID="ivo://ivoa.net/std/TAP#aux"><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://tapvizier.cds.unistra.fr/TAPVizieR/tap</accessURL></interface></capability><capability xsi:type="cs:ConeSearch" standardID="ivo://ivoa.net/std/ConeSearch"><description>Cone search capability for table J/AJ/150/111/table2 (from the first Data Release (DR1) of the Keck Observatory Database of Ionized Absorption toward Quasars (KODIAQ))</description><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/150/111/table2?</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/150/111/table2?</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/150/111/table2?</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface><maxSR>180.0</maxSR><maxRecords>50000</maxRecords><verbosity>true</verbosity><testQuery><ra>2.3809583</ra><dec>2.2854167</dec><sr>0.005555555555555556</sr></testQuery></capability><coverage><spatial>6/6 8 523 532 993 2348 2611 4259 4481 4623 4820 4946 4950 5035 5039 5051 5272 5306 5333 5696 5723 5886 6010 6028 6030 6042 6062 6070 6106 6205 6252 6403 6425 6565 6579 6591 6644 7168 7291 7500 7709 8303 8343 8552 9112 9138 9272 9464 9730 9801 9806 9827 9940 9946 9973 10074 10103 10188 10312 10405 10602 10698 10752 10843 10992 10994 11092 11107 11113 11283 11321 11339 11418 11581 11596 11786 11796 15351 16500 16652 16654 16717 17239 17244 17299 17317 17510 17693 17749 17772 17778 17813 17895 18029 18030 18060 18101 18200 18366 18389 18406 18408 18521 18582 18765 18880 19087 19408 19461 19494 19682 19688 19734 19779 20016 20032 20202 20450 21180 22715 23099 23203 23210 25285 25599 25932 26166 26170 26269 26429 26533 26553 26603 26882 27247 27365 27423 27437 27485 27508 27510 27549 27578 27654 27667 27687 27845 28281 28356 28532 28614 29795 31331 31551 31622 35772 36495 36784 40274 43903 47941 48474 48498 48567 48610 49086 49100</spatial><footprint ivo-id="ivo://ivoa.net/std/moc">https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/150/111?format=ascii</footprint><waveband>Optical</waveband></coverage><tableset><schema><name>default</name><table><name>J/AJ/150/111/table2</name><description>from the first Data Release (DR1) of the Keck Observatory Database of Ionized Absorption toward Quasars (KODIAQ)</description><column><name>recno</name><description>Record number assigned by the VizieR team.
