cds-question@unistra.frh-ii-regionsastrophysical-masersradio-astronomyradio-sourcesWe have mapped the water maser emission associated with the infrared centers IRS 1 and IRS 3 of the NGC 2071 IR star-forming region at four epochs over ~4 months with the Very Long Baseline Array. We detected 269 maser features with ~1km/s line widths and measured 30 proper motions. In each infrared center, the water maser emission appears to trace parts of a protostellar disk and collimated outflow.2002ApJ...581..325Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/581/325CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJ/463/205 : CS and NH3 Survey of H2O Maser Emission (Anglada+ 1996)Table 1: Journal of 1996 VLBA Observationshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/581/325https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/581/325http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/581/325https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/581/325https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/581/325http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/581/325GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapRadiodefaultJ/ApJ/581/325/table2Water Maser Features in NGC 2071 IRS1 & IRS3recnoRecord number assigned by the VizieR team.
