Recent photometric and parallax measurements of stars in the Upper Scorpius subgroup of the Sco-Cen OB association suggest a distance for the cloud between 120 and 140 parsecs. Star formation is ongoing in the dense cores of L1688 with a median age for young stellar objects of 0.3Myr. The surface population appears to have a median age of 2-5Myr and merges with low mass stars in the Upper Scorpius subgroup. Making use of the most recent X-ray and infrared photometric surveys and spectroscopic surveys of L1688, we compile a list of over 300 association members with counterparts in the 2MASS catalog. Membership criteria, such as lithium absorption, X-ray emission, and infrared excess, cover the full range of evolutionary states for young stellar objects. Spectral energy distributions are classified for many association members using infrared photometry obtained from the Spitzer Space Telescope.</description><source format="bibcode">2008yCat.2289....0W</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/II/289</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/ApJ/438/813">J/ApJ/438/813 : Stellar population in {rho} Oph cloud core (Strom+, 1995)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/372/173">J/A+A/372/173 : ISOCAM observations of the rho Ophiuchi cloud (Bontemps+, 2001)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJ/566/993">J/ApJ/566/993 : rho Ophiuchus (LDN 1688) cluster NICMOS imaging (Allen+, 2002)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJ/613/393">J/ApJ/613/393 : X-ray and radio sources in {rho} Oph Core A (Gagne+, 2004)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/AJ/130/1733">J/AJ/130/1733 : Optical spectroscopy of {rho} Oph stars (Wilking+, 2005)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/AJ/131/3016">J/AJ/131/3016 : Low-mass objects in Upper Scorpius (Slesnick+, 2006)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/452/245">J/A+A/452/245 : Near-IR photometry of PMS stars in rho Oph (Natta+, 2006)</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=II/289</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/VizieR-2?-source=II/289</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=II/289</mirrorURL></interface></capability><capability><interface xsi:type="vs:ParamHTTP"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/votable?-source=II/289</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/votable?-source=II/289</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/votable?-source=II/289</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 II/289/table1 (LDN 1688 cloud members)</description><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/conesearch/II/289/table1?</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/conesearch/II/289/table1?</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/conesearch/II/289/table1?</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface><maxSR>180.0</maxSR><maxRecords>50000</maxRecords><verbosity>true</verbosity><testQuery><ra>246.2355</ra><dec>-24.9939444</dec><sr>0.005555555555555556</sr></testQuery></capability><coverage><spatial>6/42958 42959 42980 42981 42983 42992</spatial><spectral>1.1166583743361574e-19 1.7003137259100215e-19</spectral><footprint ivo-id="ivo://ivoa.net/std/moc">https://cdsarc.cds.unistra.fr/viz-bin/moc/II/289?format=ascii</footprint><waveband>Infrared</waveband></coverage><tableset><schema><name>default</name><table><name>II/289/table1</name><description>LDN 1688 cloud members</description><column><name>recno</name><description>Record number assigned by the VizieR team.
