cds-question@unistra.frh-ii-regionschemical-abundancesWe present a new analysis of the main empirical calibrators of oxygen abundance for ionised gas nebulae. With that aim we have compiled an extensive sample of objects with emission line data including the near IR [SIII] lines and the weak auroral lines which allow for the determination of the gas electron temperature. For all the objects the oxygen abundances have been derived in a homogeneous way, using the most recent sets of atomic coefficients and taking into the account the effect of particle density on the temperature of O^+^. The residuals between directly and empirically-derived abundances as a function of abundance have been studied. A grid of photo-ionisation models, covering the range of physical properties of the gas, has been used to explain the origin of the uncertainties affecting each abundance calibrator. The range of validity for each abundance parameter has been identified and its average uncertainty has been quantified.2005MNRAS.361.1063Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/361/1063CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/91/285 : HII galaxies spectrophotometric catalogue (Terlevich+, 1991)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/361/1063https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/361/1063http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/361/1063https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/361/1063https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/361/1063http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/361/1063GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/361/1063/table2 (Density, temperatures and oxygen abundances)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/361/1063/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/361/1063/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/361/1063/table2?GETtext/xml+votable180.050000true24.14791715.8363890.0055555555555555566/38 1930 2154-2155 2241 3042 4276 4406 5203 5419 5556 5607 5964 6005 6010-6011 6034 6075 6087 6098 7243 7251-7252 7261 7263 7273 7281 7381 7683 7692 7743 7878 7926 7946 8028 8713 9112 9115 9182 9190 9852 9855 9966 10043 10106 10186 10348 10399 10431-10432 10441-10442 10472 10481 10527 10561 10587 10632 10689 10769 10811 10821 10881 10911 10970 11027 11031 11132 11137 11177-11178 11180 11239 11355 11382 11428 11434 11615 11782 15461 15473 16441 16519 16686 16770 17771 17816 17865 17867 18002 18053 18099 18198 18398 18793 18809 18858 20388 21439 21550 22828 23078 23566 24510 24624 24685 24696 24733 24859 25045 25169 25344 25594 25659 25734 25737 25739 26205 26278 26289 26362 26963-26964 26971 26992 27243 27457 27657 27677 27713 27729 27765 27773 27775 27884 27945 28077 28913 29116 29718 31487 33051 33078 33090 33094 33096 33098 33102 33112-33113 33123 33294 33304 33306 33317 33966 34168 34243 34426 34478 34498 34576 34857 34955 35189 35243 35538 36258 37923 38016 38390 38821 38829 38833 39574 39602 39611 39628 39804 40255 43420 43429 43635 43754 43788 43829 43904 43920 43976 44236 46445 46545 47701https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/361/1063?format=asciiOpticaldefaultJ/MNRAS/361/1063/refsBibliographic sources for flux data (table 1)ComCommentscharrecnoRecord number assigned by the VizieR team.
