cds-question@unistra.frh-ii-regionsradio-astronomyh-i-line-emissionWe resolve the kinematic distance ambiguity for 266 inner Galaxy HII regions out of a sample of 291 using existing HI and ^13^CO sky surveys. Our sample contains all HII regions with measured radio recombination line emission over the extent of the ^13^CO Boston University-Five College Radio Astronomy Observatory Galactic Ring Survey (18<l<55{deg} and |b|<1) and contains ultra compact (UC), compact, and diffuse HII regions. We use two methods for resolving the distance ambiguity for each HII region: HI emission/absorption (HI E/A) and HI self-absorption (HI SA).2009ApJ...690..706Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/690/706CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/112 : Catalog of Star-Forming Regions in the Galaxy (Avedisova, 2002)VIII/58 : A Survey of Radio H II Regions in the Northern Sky (Lockman+ 1989)VII/50 : CO Radial Velocities Toward Galactic H II Regions (Blitz+ 1982)J/ApJS/181/255 : CO in galactic HII regions (Anderson+, 2009)J/ApJ/626/887 : HI clouds in Southern Galactic Plane Survey (Kavars+, 2005)J/A+A/397/133 : Star-forming complexes in the Galaxy (Russeil+, 2003)J/ApJS/140/331 : High-velocity HI observations at 21cm (Lockman+, 2002)http://www.bu.edu/galacticring : Galactic Ring Survey (GRS) home pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/690/706https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/690/706http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/690/706https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/690/706https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/690/706http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/690/706GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/690/706/regions (HII region kinematic parameters and distances)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/690/706/regions?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/690/706/regions?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/690/706/regions?GETtext/xml+votable180.050000true274.4198-15.87960.0055555555555555565/7377 7383 7564 7604 7654 6/29118 29119 29461 29504 29505 29522 29523 29528 29529 30218 30219 30222 30241 30244 30245 30247 30262 30263 30268 30269 30312 30313 30315 30317 30318 30319 30330 30405 30420 30422 30423 30594 30595 30600 30601 30604 30605 30622 30623 30644 30645 30691 30692 30694 30695 30701 30706 30707 30712 30715 30716 30718 30719https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/690/706?format=asciiRadiodefaultJ/ApJ/690/706/regionsHII region kinematic parameters and distancesrecnoRecord number assigned by the VizieR team.
