cds-question@unistra.frgalaxiesspectroscopyh-ii-regionschemical-abundancesOur aims are to estimate the validity of empirical methods, such as R23, R23-P, log([NII]/H{alpha}) (N2), log[([OIII]/H{beta})/([NII]/H{alpha}] (O3N2), and log([SII]/H{alpha}) (S2), and to re-derive (or add) the calibrations of R23, N2, O3N2, and S2 indices for oxygen abundances on the basis of a large sample of galaxies with Te-based abundances. We determined the gas-phase oxygen abundance for a sample of 695 galaxies and HII regions with reliable detections of [OIII]4363, using the reliable and direct temperature-sensitive (Te) method of measuring metallicity. We selected 531 star-forming galaxies from the SDSS-DR4 database with strong emission lines, including [OIII]4363 detected at a signal-to-noise ratio higher than 5{sigma}, as well as 164 galaxies and HII regions from the literature with Te measurements. The O/H abundances were derived from a two-zone model for the temperature structure, assuming a relationship between high ionization and low ionization species.2007A&A...462..535Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/462/535CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tohttp://www.sdss.org/ : SDSS Home PageII/267 : The SDSS Photometric Catalog, Release 4 (Adelman-McCarthy+, 2006)II/276 : The SDSS Photometric Catalog, Release 5 (Adelman-McCarthy+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/462/535https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/462/535http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/462/535https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/462/535https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/462/535http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/462/535GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/462/535/table1 (The characteristic parameters of the SDSS galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/462/535/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/462/535/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/462/535/table1?GETtext/xml+votable180.050000true145.89129171.11650.0055555555555555566/0-2 4096 4109 4122 4164 4179 4195 4258 4798 4811 4833 4843 4991 5018 5028 5033 5057 5079 5083-5084 5097 5107 5109 5111 5372 5488 5497 5556-5557 5578 5599 5604 5626 5631 5659 5690 5694 5703 5706 5715 5721 5737 5768-5769 5781 5814 5853 5859 5862 5874 5907 5954 5990-5991 5998 6009 6027 6050 6052 6076 6085 6087 6104 6119 6142 6161 6169 6215 6232 6254 6256-6257 6269 6385 6399 6449 6452 6467 6475 6489 6508 6514 6518 6524 6533 6544 6559 6581 6599 6610 6623 7210 7226 7237 7241 7250 7252 7255 7266 7280 7291-7292 7298 7315 7320 7322 7324 7372 7426 7434 7441 7472-7473 7487 7496 7505 7523 7532 8201 8205 8210 8226 8228 8232 8739 8742 9053 9063 9071 9181 9213 9223 9265 9332 9378 9383 9407 9453 9474 9512 9613 9636 9642 9644 9734 9748 9760 9771 9825-9826 9842 9885 9918 9923 9931 9944 9955 9962 9974 9980 9989 10017 10020 10028 10106 10144 10147 10211 10217 10222 10493 10524 10562 10574 10593 10601 10666 10676 10680 10688 10691 10697 10700 10703 10750 10835 10902 10950-10951 10975 11033 11050 11070 11098 11108 11115 11126 11137 11141 11172-11173 11207 11211 11213 11222 11238 11241 11247 11355 11364 11389 11411 11428 11436 11438 11450 11456 11480 11489 11515 11597 11787 11790 11822 11841 11848 11907 11909 11945-11946 12406 16893 17256 17293 17303 17503 17511 17518 17528 17550 17564 17566 17573 17584 17601 17661 17727 17745 17748 17750-17751 17754-17755 17758 17761-17762 17769 17772 17811 17815 17820 17837 17858 17982 17999 18002 18009-18010 18022-18025 18027-18029 18061 18069 18083 18088 18091-18092 18113 18301 18393 18413-18414 18688 18767 18773 18775-18776 18779 18785 18789 18792 18795 18797 18840 18843-18845 18853 18858 18860 18953 18956 18960 19007 19022 19028 19031 19033 19035-19036 19038 19045 19050 19056 19096 19099-19100 19105 19111 19122 19389 19409 19737 19739 19762 19841 21846 21853 21885 21976 23052 23102 23182 23186-23187 23192-23193 23195-23197 23210 23212-23213 25599 25937 25943 25947 25960 25966 25976 26000 26014 26025 26044 26087 26165 26185 26204 26225 26232 26289 26295 26300 26304 26333 26337 26339 26353 26370 26398 26400 26462 26526 26974 26992 27006 27034 27038 27057 27067 27081-27082 27089 27102 27227 27291 27303 27324 27330 27341 27366 27396 27441 27462-27463 27467 27499 27512 27515 27525 27547-27548 27562 27569 27581-27582 27598 27661 27681 27691 27698 27702 27741 27743 27764 27783 27810 27825 27827 27872 30035-30036 30065 30975 31291 31319 31341 31387-31388 31398 31400 31436 31475 31488 32413 32431 32484 32497 36715-36716 36723 36727 36766 36779 36781 36793 36801 49016 49099 49101 49151https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/462/535?format=asciiOpticaldefaultJ/A+A/462/535/table1The characteristic parameters of the SDSS galaxiesrecnoRecord number assigned by the VizieR team.
