cds-question@unistra.frsurveysgalaxiescatalogschemical-abundancesThe study of the integrated properties of star-forming galaxies is central to understand their formation and evolution. Some of these properties are extensive and therefore their analysis require totally covering and spatially resolved observations. Among these properties, metallicity can be defined in spiral discs by means of integral field spectroscopy (IFS) of individual HII regions. The simultaneous analysis of the abundances of primary elements, as oxygen, and secondary, as nitrogen, also provides clues about the star formation history and the processes that shape the build-up of spiral discs. Our main aim is to analyse simultaneously O/H and N/O abundance ratios in HII regions in different radial positions of the discs in a large sample of spiral galaxies to obtain the slopes and the characteristic abundance ratios that can be related to their integrated properties. We analysed the optical spectra of individual selected HII regions extracted from a sample of 350 spiral galaxies of the CALIFA survey. We calculated total O/H abundances and, for the first time, N/O ratios using the semi-empirical routine HII-CHI-MISTRY, which, according to Perez-Montero (2014MNRAS.441.2663P), is consistent with the direct method and reduces the uncertainty in the O/H derivation using [NII] lines owing to the dispersion in the O/H-N/O relation. Then we performed linear fittings to the abundances as a function of the de-projected galactocentric distances.2016A&A...595A..62Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/595/A62CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/576/A135 : CALIFA DR2 (Garcia-Benito+, 2015)J/A+A/587/A70 : CALIFA face-on spiral galaxies oxygenhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/595/A62https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/595/A62http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/595/A62https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/595/A62https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/595/A62http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/595/A62GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/595/A62/table1 (List of the analysed CALIFA galaxies with their effective radii, inclinations, and the number of HII regions used to calculate their O/H and N/O slopes and the values at the effective radius of the gradients)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/595/A62/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/595/A62/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/595/A62/table1?GETtext/xml+votable180.050000true7.8674917-19.76131110.0055555555555555566/56 568 721 738 909 995 2206 2251 2274 2290 2641 4053 4178 4342 4445 4454 4507 4511 4799 4843 4912 5028 5332 5579 5593 6214 6241 6261 6270 6342 6362 6366 7204 7309 7559 7584 7824 7834 7844 8045 8331 8458 8480 8492 8498 8522 8536 8552 8562-8563 8621 8646 8743 8752 8883 8921-8922 8973 9101 9124 9187 9216 9220 9622 9628 9718 9859 9875 9883 9974 10025 10111 10213 10221 10280 10380-10381 10398 10414 10422 10511 10518 10524 10566 10570 10577 10588 10595 10609 10612 10621 10629 10661-10662 10674 10705 10711 10727 10739-10740 10778 10987 11112 11272 11290 11342 11377 11392 11396 11433 11451 11793 11800 11832 11944 13316 13381 13426 15004 16696 16702 16788 16793 17234 17238 17350 17398 17486 17499 17509 17511 17578 17819 18069 18081 18173 18242 18300 18383 18775 18779 18781 18800 18838 18854 18932 18941 19186 19260 19267 19487 19489 19515 19537-19538 19589 19618 19696 19749 19848 19954 19983 19996 20009 20020 20023 20031 20040 20193 20254 20279 20417-20418 22652 22741 23401 27559 27567 27719 27748 28458 28513 28522 28579 28617 28639 29973 31628 31688-31689 32478 32482 48880 49150https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/595/A62?format=asciidefaultJ/A+A/595/A62/table1List of the analysed CALIFA galaxies with their effective radii, inclinations, and the number of HII regions used to calculate their O/H and N/O slopes and the values at the effective radius of the gradientsnHIINumber of HII regionsmeta.numberintrecnoRecord number assigned by the VizieR team.
