cds-question@unistra.frastrophysical-masersradio-astronomyradial-velocityA catalog of class I methanol masers discovered so far in the Southern and Northern hemispheres is presented. The catalog contains 160 sources. A statistical analysis shows that, within 2' of the telescope pointing (which corresponds approximately to the field of view of single antennas used in search surveys), 50% of class I methanol masers are associated with objects characteristic of active starforming regions: IRAS sources, ultracompact HII regions, and dense gas dust clouds, as well as OH and H2O interstellar masers. At the same time, bipolar out flows (which could play an active part in pumping the methanol masers) are associated with fewer than 25% of class I methanol masers. In 72% of cases, class I methanol masers are associated with class II methanol maser sources. These results suggest that methanol maser condensations are more appropriately classified by the transition type (that is, the pumping mechanism) than their association with other astronomical objects.2007AZh....84..579Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AZh/84/579CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AZh/71/37 : Thermal Methanol from 33 Clouds at 48GHz (Slysh+, 1994)J/AZh/72/22 : A 95GHz Survey of Methanol Masers (Valtts+, 1995)J/A+AS/110/81 : Methanol masers towards IRAS sources (van der Walt+ 1995)J/A+A/314/615 : Maps of the 36 GHz methanol emission (Liechti+, 1996)J/MNRAS/291/261 : Methanol maser of IRAS-selected sources (Walsh+ 1997)J/A+AS/134/115 : Medicina 6.7GHz methanol masers survey (Slysh+ 1999)J/A+A/432/737 : 6.7GHz Methanol Masers General Catalogue (Pestalozzi+, 2005)J/A+A/414/235 : OH maser emission from star forming regions (Szymczak+ 2004)J/MNRAS/359/1498 : Class I and class II methanol masers (Ellingsen+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AZh/84/579https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AZh/84/579http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AZh/84/579https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AZh/84/579https://vizier.iucaa.in/viz-bin/votable?-source=J/AZh/84/579http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AZh/84/579GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AZh/84/579/catalog (Catalog of class I methanol masers)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AZh/84/579/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/AZh/84/579/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AZh/84/579/catalog?GETtext/xml+votable180.050000true36.473205962.06960880.0055555555555555566/862 3649 14299 14317 14353 14594 14622 14655 14704 15430 15479 15667 15759 15965 21439 22805 22855 22873 22876 23637 23969 24325 24554 28808 28825 28829 28830 28891 28912 28919 29070 29091 29094 29096 29097 29101 29103 29112 29113 29115 29116 29118 29160 29461 29510 29513 29532 29533 30218 30219 30222 30245 30256 30259 30262 30269 30319 30405 30416 30417 30616 30618 30622 30624 30644 30694 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 43021https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AZh/84/579?format=asciiOpticalRadiodefaultJ/AZh/84/579/catalogCatalog of class I methanol masersSeq[1/160] Sequential numbermeta.recordintrecnoRecord number assigned by the VizieR team.
