cds-question@unistra.frgalaxiesh-ii-regionschemical-abundancesgalaxy-classification-systemsWe investigate the oxygen and nitrogen abundance distributions across the optical disks of 130 nearby late-type galaxies using around 3740 published spectra of HII regions. We use these data in order to provide homogeneous abundance determinations for all objects in the sample, including HII regions in which not all of the usual diagnostic lines were measured. Examining the relation between N and O abundances in these galaxies we find that the abundances in their centers and at their isophotal R_25_ disk radii follow the same relation. The variation in N/H at a given O/H is around 0.3dex. We suggest that the observed spread in N/H may be partly caused by the time delay between N and O enrichment and the different star formation histories in galaxies of different morphological types and dimensions. We study the correlations between the abundance properties (central O and N abundances, radial O and N gradients) of a galaxy and its morphological type and dimension.2014AJ....147..131Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/147/131CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/139 : The SDSS Photometric Catalog, Release 9 (Adelman-McCarthy+, 2012)J/ApJS/153/429 : SDSS strong emission line HII galaxies (Kniazev+, 2004)J/MNRAS/424/2316 : Abundances in HII regions (Pilyugin+, 2012)http://atlas.obs-hp.fr/hyperleda/ : HyperLeda databasehttp://www.sdss3.org/ : The SDSS-III Web sitehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/147/131https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/147/131http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/147/131https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/147/131https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/147/131http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/147/131GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/147/131/galaxies (Properties , and abundances of our galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/147/131/galaxies?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/147/131/galaxies?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/147/131/galaxies?GETtext/xml+votable180.050000true2.4864584.6125280.0055555555555555566/955 2051 2142 2155 2320 2347 2372 2709 3042 3506 4359 4439 4511 5142 5202 5492 5545 5580 5596 5715 5751 5966 5976 6034 6353 6619 6637 7241 7498 7584 7604 7606 7743 7799 7898 8064 8113 8642 9190 9277 10475 10755 10761 10769 10841 10856 10901 10905 10924 10977 10991 11027 11188 11387 11434 13522 15260 15592 16441 16655 17717 17745 17753 17754 17755 17912 18002 18011 18013 18271 18394 18398 18800 18930 18932 18941 18943 19481 19749 19754 19841 19978 19981 20090 22751 22956 24912 25599 26068 26178 26303 26331 26472 26535 27030 27243 27373 27514 27643 27728 27803 27861 27918 27926 27945 27955 28035 28123 28496 28535 31880 33193 33920 34028 34404 34531 35514 35536 35993 36258 37429 38390 38655 40328 43881 45748 46660https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/147/131?format=asciiOpticaldefaultJ/AJ/147/131/galaxiesProperties , and abundances of our galaxiesrecnoRecord number assigned by the VizieR team.
