cds-question@unistra.frplanetary-nebulaechemical-abundancesRecombination lines (RLs) of C II, N II, and O II in planetary nebulae (PNs) have been found to give abundances that are much larger in some cases than abundances from collisionally excited forbidden lines (CELs). The origins of this abundance discrepancy are highly debated. We present new spectroscopic observations of O II and C II recombination lines for six planetary nebulae.2005ApJS..157..371Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/157/371CatalogResearchIsServedByTAP VizieR generic servicerelated-toV/84 : Strasbourg-ESO Catalogue of Galactic Planetary Nebulae (Acker+, 1992)J/A+A/405/627 : Angular dimensions of 312 planetary nebulae (Tylenda+, 2003)J/ApJS/139/199 : Catalog of distances of planetary nebulae (Phillips, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/157/371https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/157/371http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/157/371https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/157/371https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/157/371http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/157/371GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/ApJS/157/371/table2Observed fluxes relative to H{Beta}=100.0recnoRecord number assigned by the VizieR team.
