cds-question@unistra.frgalaxiescatalogsh-ii-regionschemical-abundancesgalaxy-classification-systemsWe construct maps of the oxygen abundance distribution across the discs of 88 galaxies using Calar Alto Legacy Integral Field Area survey (CALIFA) Data Release 2 (DR2) spectra. The position of the centre of a galaxy (coordinates on the plate) was also taken from the CALIFA DR2. The galaxy inclination, the position angle of the major axis, and the optical radius were determined from the analysis of the surface brightnesses in the Sloan Digital Sky Survey (SDSS) g and r bands of the photometric maps of SDSS Data Release 9. We explore the global azimuthal abundance asymmetry in the discs of the CALIFA galaxies and the presence of a break in the radial oxygen abundance distribution. We found that there is no significant global azimuthal asymmetry for our sample of galaxies, i.e. the asymmetry is small, usually lower than 0.05dex. The scatter in oxygen abundances around the abundance gradient has a comparable value, <~0.05dex. A significant (possibly dominant) fraction of the asymmetry can be attributed to the uncertainties in the geometrical parameters of these galaxies. There is evidence for a flattening of the radial abundance gradient in the central part of 18 galaxies. We also estimated the geometric parameters (coordinates of the centre, the galaxy inclination and the position angle of the major axis) of our galaxies from the analysis of the abundance map. The photometry-map-based and the abundance-map-based geometrical parameters are relatively close to each other for the majority of the galaxies but the discrepancy is large for a few galaxies with a flat radial abundance gradient.2016MNRAS.462.2715Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/462/2715CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/576/A135 : CALIFA DR2 (Garcia-Benito+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/462/2715https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/462/2715http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/462/2715https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/462/2715https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/462/2715http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/462/2715GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/462/2715/tablea1 (The adopted general properties of our of the CALIFA galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/462/2715/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/462/2715/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/462/2715/tablea1?GETtext/xml+votable180.050000true1.815937527.70809170.0055555555555555566/721 738 2206 2251 2274 2641 4053 4178 4342 4445 4507 4511 5332 5533 5579 5593 6240 6261 6342 7824 7844 8552 8743 9628 9718 9875 9883 9891 10113 10183 10515 10612 10627 10629 10740 11070 11164 11290 11396 11544 11832 11944 13316 13381 13426 15004 16788 17234 17350 17398 17751 18069 18071 18383 18800 18932 19027 19186 19227 19267 19487 19489 19537 19618 19996 20020 20023 20031 20193 20279 20417-20418 23337 23401 27559 27719 28513 28617 31628 31642 31688-31689 32478 32559 48880 49121 49150https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/462/2715?format=asciiOpticaldefaultJ/MNRAS/462/2715/tablea1The adopted general properties of our of the CALIFA galaxiesrecnoRecord number assigned by the VizieR team.
