We have also compared the data with TeV gamma-ray sources. The analyzed region covers -12{deg}&lt;=l&lt;=12{deg} and -1.5{deg}&lt;=b&lt;=1.5{deg} for ^12^CO, and -6{deg}&lt;=l&lt;=8{deg} and -1{deg}&lt;=b&lt;=1{deg} for ^13^CO. As a result, we identified 167 IRAS point sources, 73 recombination line sources, 58 maser sources, 107 radio continuum sources, and 77 molecular line sources associated with 169 positions with the CO emission.</description><source format="bibcode">2010PASJ...62..557T</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/PASJ/62/557</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/A+A/391/967">J/A+A/391/967 : H2O and SiO masers in the Galactic center (Sjouwerman+, 2002)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/PASJ/56/261">J/PASJ/56/261 : SiO maser survey in Galactic center (Deguchi+, 2004)</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/PASJ/62/557</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PASJ/62/557</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PASJ/62/557</mirrorURL></interface></capability><capability><interface xsi:type="vs:ParamHTTP"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PASJ/62/557</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/votable?-source=J/PASJ/62/557</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PASJ/62/557</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/PASJ/62/557/table1 (List of CO clouds associated with astronomical objects.)</description><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASJ/62/557/table1?</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/conesearch/J/PASJ/62/557/table1?</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASJ/62/557/table1?</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface><maxSR>180.0</maxSR><maxRecords>50000</maxRecords><verbosity>true</verbosity><testQuery><ra>258.2161</ra><dec>-38.6808</dec><sr>0.005555555555555556</sr></testQuery></capability><capability xsi:type="cs:ConeSearch" standardID="ivo://ivoa.net/std/ConeSearch"><description>Cone search capability for table J/PASJ/62/557/table2 (CO observational parameters)</description><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASJ/62/557/table2?</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/conesearch/J/PASJ/62/557/table2?</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASJ/62/557/table2?</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface><maxSR>180.0</maxSR><maxRecords>50000</maxRecords><verbosity>true</verbosity><testQuery><ra>258.2161</ra><dec>-38.6808</dec><sr>0.005555555555555556</sr></testQuery></capability><coverage><spatial>5/7203 7206-7207 7228-7229 10612 10615 6/24507 28802-28803 28806 28808 28811 28818 28836 28852 28874-28875 28878 28890-28891 28896 28899-28901 28925 29090-29092 29094 29096-29097 29100 29102 42436-42437 42439 42441 42444-42445 42447 42454-42458</spatial><footprint ivo-id="ivo://ivoa.net/std/moc">https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PASJ/62/557?format=ascii</footprint><waveband>Radio</waveband></coverage><tableset><schema><name>default</name><table><name>J/PASJ/62/557/table1</name><description>List of CO clouds associated with astronomical objects.</description><column><name>recno</name><description>Record number assigned by the VizieR team.
