cds-question@unistra.frinterstellar-mediumastrophysical-masersradio-astronomyRecent studies of methanol and ground-state OH masers at very high spectral resolution have shed new light on small-scale maser processes. The nearby source W3(OH), which contains numerous bright masers in several different transitions, provides an excellent laboratory for high spectral resolution techniques. We present a model of W3(OH) based on European VLBI Network (EVN) observations of the rotationally excited 6030 and 6035MHz OH masers taken at 0.024km/s spectral resolution.2007ApJ...668..331Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/668/331CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/647/418 : Ground-state OH masers in W3(OH) study (Fish+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/668/331https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/668/331http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/668/331https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/668/331https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/668/331http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/668/331GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/668/331/table1 (Detected 6030 and 6035MHz masers in W3(OH))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/668/331/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/668/331/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/668/331/table1?GETtext/xml+votable180.050000true36.765402561.87370860.005555555555555556Cone search capability for table J/ApJ/668/331/table2 (Zeeman pairs and associations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/668/331/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/668/331/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/668/331/table2?GETtext/xml+votable180.050000true36.765403161.87370810.0055555555555555566/3649https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/668/331?format=asciiRadiodefaultJ/ApJ/668/331/table1Detected 6030 and 6035MHz masers in W3(OH)recnoRecord number assigned by the VizieR team.
