cds-question@unistra.frchemical-abundancesh-ii-regionsinfrared-astronomyspectroscopySix HII regions at galactocentric distances of R=10-15kpc have been observed in the far-IR emission lines of [OIII] (52{mu}m, 88{mu}m), [NIII] (57{mu}m), and [SIII] (19{mu}m) using the Kuiper Airborne Observatory. These observations have been combined with Very Large Array radio continuum observations of these sources to determine the abundances of O++, N++, and S++ relative to hydrogen. In addition, eight of the most recent sets of measurements of ionic line strengths in HII regions have been reanalyzed in order to attempt to reconcile differences in optical versus far-IR abundance determinations. We have in total 168 sets of observations of 117 HII regions in our analysis.2006ApJS..162..346Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/162/346CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/50 : CO Radial Velocities Toward Galactic HII Regions (Blitz+ 1982)VIII/58 : Survey of Radio HII Regions in the Northern SkyJ/A+A/275/67 : Velocity Field of the outer Galaxy (Brand+ 1993)J/A+A/171/261 : Radio Recombination Lines of Southern HII RegionsJ/AJ/106/1906 : NGC 6611: A Cluster Caught in the Act (Hillenbrand+ 1993)J/AJ/113/1733 : Orion Nebula Cluster population (Hillenbrand 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/162/346https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/162/346http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/162/346https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/162/346https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/162/346http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/162/346GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/162/346/table4 (HII region distances)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/162/346/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/162/346/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/162/346/table4?GETtext/xml+votable180.050000true266.45-28.84833330.005555555555555556Cone search capability for table J/ApJS/162/346/table6 (Final abundances)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/162/346/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/162/346/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/162/346/table6?GETtext/xml+votable180.050000true266.45-28.84833330.0055555555555555566/1781 1811 1814 1839 1848 1930 1956 3011 3175 3606 3649 3730 14263 14267 14293 14304 14306 14307 14314 14317 14344 14359 14406 14430 14453 14624 14633 14641 14644 14704 14716 15363 15435 15461 15473 15477 20849 21439 21504 21550 21671 22078 22080 22115 22167 22208 22209 22252 23645 23674 23760 23767 23969 23982 24426 28808 28827 28830 28831 28890 28918 29091 29096 29100 29101 29102 29114 29116 29119 29463 29505 29513 29515 29535 30219 30259 30262 30263 30312 30318 30420 30644 30694 37850 37872 37886 37894 37897 37900 37923 37924 38016 39386 39804 41772 41817 41820 42172 42228 42391 42436 42445 43019https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/162/346?format=asciiInfrareddefaultJ/ApJS/162/346/table4HII region distancesrecnoRecord number assigned by the VizieR team.
