Currently, the catalog contains 206 objects, selected from publications through 2011 inclusive. The data from the survey of Chen et al. (2011, Cat. J/ApJS/196/9), performed specifically for objects EGO, which form a new specific catalog, are not included. The MMI/SFR objects were identified with emission and absorption objects in the near IR, detected during the MSX and Spitzer space missions. Seventy-one percent of Class I methanol masers that emit at 44GHz and fall within the Galactic longitude range surveyed by Spitzer (GLIMPSE) are identified with Spitzer Dark Clouds (SDCs), and 42% with Extended Green Objects (EGOs). It is possible that Class I methanol masers arise in isolated, self-gravitating clumps, such as SDCs, at certain stages of their evolution. A sample of SDCs is proposed as a new target list for Class I methanol maser searches. A detailed statistical analysis was carried out, taking into account the characteristics of the regions of MMI/SFR formation presented in the catalog.</description><source format="bibcode">2012AZh....89..611B</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/AZh/89/611</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/AZh/84/579">J/AZh/84/579 : Catalog of Class I methanol masers (Val'tts+, 2007)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJS/196/9">J/ApJS/196/9 : 95GHz methanol maser survey toward GLIMPSE EGOs (Chen+, 2011)</relatedResource><relatedResource>http://www.asc.rssi.ru/MMI : Class I Methanol Maser Catalog</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/AZh/89/611</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AZh/89/611</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AZh/89/611</mirrorURL></interface></capability><capability><interface xsi:type="vs:ParamHTTP"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AZh/89/611</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/votable?-source=J/AZh/89/611</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AZh/89/611</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/AZh/89/611/table1 (Identifications of Class I methanol masers with IR objects, bipolar outflows, and UC HII regions)</description><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AZh/89/611/table1?</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/conesearch/J/AZh/89/611/table1?</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AZh/89/611/table1?</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface><maxSR>180.0</maxSR><maxRecords>50000</maxRecords><verbosity>true</verbosity><testQuery><ra>7.1779167</ra><dec>56.7019444</dec><sr>0.005555555555555556</sr></testQuery></capability><coverage><spatial>6/862 1307 2973 2996 3061 3649 13050 13230 14287 14299 14307 14314 14315 14317 14353 14355 14594 14630 14647 14655 14689 14696 14704 15430 15479 15667 15759 15794 21436 21439 22805 22855 22873 22876 23637 23773 23969 24325 24365 24507 24554 28808 28824 28825 28829 28830 28891 28912 28919 29070 29091 29094 29096 29097 29101 29103 29112 29113 29115 29116 29118 29160 29461 29507 29508 29510 29513 29529 29532 29533 29535 30218 30219 30222 30241 30244 30245 30256 30259 30262 30269 30313 30318 30319 30405 30416 30417 30420 30423 30425 30604 30616 30618 30622 30624 30644 30694 30716 37846 37850 37897 41655 41677 41772 41777 41778 41780 41804 41805 41812 41813 41815 41817 41820 41824 42159 42169 42170 42171 42172 42207 42210 42211 42214 42224 42230 42379 42381 42387 42390 42391 42396 42417 42441 42444 42449 42451 42455 42456 42457 42496 42497 42498 42981 43013 43021</spatial><footprint ivo-id="ivo://ivoa.net/std/moc">https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AZh/89/611?format=ascii</footprint><waveband>Radio</waveband></coverage><tableset><schema><name>default</name><table><name>J/AZh/89/611/table1</name><description>Identifications of Class I methanol masers with IR objects, bipolar outflows, and UC HII regions</description><column><name>recno</name><description>Record number assigned by the VizieR team.
