cds-question@unistra.frh-ii-regionsinterstellar-mediumradio-astronomyWe report simultaneous H110{alpha} and H_2_CO line observations with the NRAO Green Bank Telescope toward 72HII regions in the Spitzer Space Telescope GLIMPSE survey area (|l|=10{deg}-65{deg} and |b|<=1{deg}). We used the H110{alpha} line to establish the velocity of the HII regions and H_2_CO absorption lines to distinguish between near and far distances. Accurate distances are crucial for the determination of physical properties of massive star formation regions.2004ApJS..154..553Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/154/553CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/154/553https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/154/553http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/154/553https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/154/553https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/154/553http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/154/553GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/154/553/sources (Observed Sources (tables 1 and 2 of the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/154/553/sources?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/154/553/sources?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/154/553/sources?GETtext/xml+votable180.050000true251.51659645.182580.0055555555555555566/9524 9532 9619 9622 9989 14359 30401 30403 30406 30412 30414 30415 30420 30437 30439 30445 30456 30458 30694 31824 31825 31827 31833 31838 31861 31862 31863 31868 31869 31871 31957 32136 32137 32138 32160 32161 32163 32169 32171 321743.2001662755499532e-24 1.9864425968556103e-21https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/154/553?format=asciiRadiodefaultJ/ApJS/154/553/sourcesObserved Sources (tables 1 and 2 of the paper)recnoRecord number assigned by the VizieR team.
