cds-question@unistra.frastrophysical-masersradio-astronomyWe have used the Effelsberg 100-meter telescope to map the 36GHz 4_-1_->3_0_E methanol transition in galactic star forming regions where methanol masers were previously detected. In most sources, the emission consists in one or several narrow (maser) features superimposed on a broader, presumably quasi-thermal component. The line shapes and positions of the narrow features are often similar to those observed in the other ClassI methanol maser transitions (at 25, 44, 84 and 95GHz), but with some exceptions. Our observations confirm that, unlike the strong ClassII methanol masers (at 12.2, and 6.6GHz), the ClassI methanol masers are offset from the compact HII regions, infrared sources and OH/H_2_O masers. In outflow sources, these are located at the edge of the molecular lobes.1996A&A...314..615Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/314/615CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/314/615https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/314/615http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/314/615https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/314/615https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/314/615http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/314/615GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/314/615/table1 (Line parameters for detected sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/314/615/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/314/615/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/314/615/table1?GETtext/xml+votable180.050000true36.47320662.0696090.005555555555555556Cone search capability for table J/A+A/314/615/table2 (Non detected sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/314/615/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/314/615/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/314/615/table2?GETtext/xml+votable180.050000true248.095237-24.4758610.0055555555555555566/3649 14063 14317 14594 14622 14704 15667 15759 21439 22805 22855 22876 23637 24325 24554 28830-28831 28912 28919 29091 29094 29101 29116 30218 30259 30262 30318-30319 30328 30618 30694 30733 42970 42981https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/314/615?format=asciiRadiodefaultJ/A+A/314/615/table1Line parameters for detected sourcesrecnoRecord number assigned by the VizieR team.
