cds-question@unistra.frh-ii-regionsnarrow-band-photometrychemical-abundancesWe present the oxygen abundance determination for 90 HII regions in the inner parts of the grand design galaxy M101. The abundances were derived employing the P method (Pilyugin, 2001A&A...369..594P). A comparison is made with previous determinations using another calibration and direct measurements of electron temperature to derive the oxygen abundance. The results show agreement with the abundances derived from the electron temperature method and also show that the older calibration is not as accurate as the P method.2004A&A...422..511Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/422/511CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/391/809 : HII regions in NGC 5457 and NGC 4395 (Cedres+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/422/511https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/422/511http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/422/511https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/422/511https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/422/511http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/422/511GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/422/511/table3Region number and derived oxygen abundance for M101 (NGC 5457)12+log(O/H)Oxygen abundance (H=12)phys.abundfloatrecnoRecord number assigned by the VizieR team.
