cds-question@unistra.frh-ii-regionsastrophysical-masersradio-astronomyAs the recent publication by Breen et al. (2013MNRAS.435..524B) found, Class II methanol masers are exclusively associated with high mass star forming regions. Based on the positions of the Class I and II methanol and H_2_O masers, UC HII regions and 4.5um infrared sources, and the center velocities (vLSR) of the Class I methanol and H_2_O masers, compared to the vLSR of the Class II methanol masers, we propose three disk-outflow models that may be traced by methanol masers. In all three models, we have located the Class II methanol maser near the protostar, and the Class I methanol maser in the outflow, as is known from observations during the last twenty years. In our first model, the H_2_O masers trace the linear extent of the outflow. In our second model, the H_2_O masers are located in a circumstellar disk. In our third model, the H_2_O masers are located in one or more outflows near the terminating shock where the outflow impacts the ambient interstellar medium. Together, these models reiterate the utility of coordinated high angular resolution observations of high mass star forming regions in maser lines and associated star formation tracers.2014IJAA....4..571Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/IJAA/4.571CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/120/283 : Water maser features in UC HII regions (Hofner+ 1996)J/ApJS/155/149 : CH_3_OH 7_0_-6_1_ A^+^ maser sources (Kurtz+, 2004)J/AZh/84/579 : Catalog of Class I methanol masers (Val'tts+, 2007)J/A+A/501/539 : RMS survey. 6cm observations of YSOs (Urquhart+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/IJAA/4.571https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/IJAA/4.571http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/IJAA/4.571https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/IJAA/4.571https://vizier.iucaa.in/viz-bin/votable?-source=J/other/IJAA/4.571http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/IJAA/4.571GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/IJAA/4.571/tables (*Positions and associated information for sources associated with 8 regions (tables 1-8 of the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/IJAA/4.571/tables?https://vizier.iucaa.in/viz-bin/conesearch/J/other/IJAA/4.571/tables?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/IJAA/4.571/tables?GETtext/xml+votable180.050000true271.562917-20.5277780.005555555555555556Cone search capability for table J/other/IJAA/4.571/table9 (*Regions with high resolution data for methanol masers only)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/IJAA/4.571/table9?https://vizier.iucaa.in/viz-bin/conesearch/J/other/IJAA/4.571/table9?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/IJAA/4.571/table9?GETtext/xml+votable180.050000true274.3454167-17.37050.0055555555555555566/14622 15430 29091 29096 29097 29101 29112 29118 29507 29508 29510 29529 29535 30218 30219 30256 30269 30404 30405 30416 30417 30420 30423 30616 30622 30644 30694https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/IJAA/4.571?format=asciiRadiodefaultJ/other/IJAA/4.571/tables*Positions and associated information for sources associated with 8 regions (tables 1-8 of the paper)recnoRecord number assigned by the VizieR team.
