cds-question@unistra.frspectroscopyh-ii-regionsinterstellar-mediumgalaxiesvisible-astronomyUsing integral field spectroscopy (IFS) observations we aim to perform a systematic study and comparison of two inner and outer HII regions samples. The spatial resolution of the IFS, the number of objects and the homogeneity and coherence of the observations allow a complete characterization of the main observational properties and differences of the regions. We analyzed a sample of 725 inner HII regions and a sample of 671 outer HII regions, all of them detected and extracted from the observations of a sample of 263 nearby, isolated, spiral galaxies observed by the CALIFA survey. We find that inner HII regions show smaller equivalent widths, greater extinction and luminosities, along with greater values of [NII] {lambda}6583/H{alpha} and [OII] {lambda}3727/[OIII] {lambda}5007 emission-line ratios, indicating higher metallicities and lower ionization parameters. Inner regions have also redder colors and higher photometric and ionizing masses, although Mion/Mphot is slightly higher for the outer regions. This work shows important observational differences between inner and outer HII regions in star forming galaxies not previously studied in detail. These differences indicate that inner regions have more evolved stellar populations and are in a later evolution state with respect to outer regions, which goes in line with the inside-out galaxy formation paradigm.2018A&A...609A.102Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/609/A102CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/559/A114 : Updated O3N2 and N2 abundance indicators (Marino+, 2013)J/A+A/573/A59 : Gas kinematics in CALIFA survey (Garcia-Lorenzo+, 2015)J/A+A/576/A135 : CALIFA DR2 (Garcia-Benito+, 2015)J/A+A/581/A103 : CALIFA survey across the Hubble sequence (Gonzalez+, 2015)J/A+A/582/A21 : Merging galaxies (mis)alignments (Barrera-Ballesteros+, 2015)J/A+A/584/A87 : CALIFA sample SFR calibration (Catalan-Torrecilla+, 2015)J/A+A/585/A47 : CALIFA color/metallicity gradients connections (Marino+, 2016)J/A+A/587/A70 : CALIFA face-on spiral galaxies oxygenJ/A+A/593/A114 : CALIFA space density distribution of galaxiesJ/A+A/595/A62 : CALIFA galaxies O/H and N/O slopes (Perez-Montero+, 2016)J/A+A/597/A48 : Stellar kinematics in CALIFA survey (Falcon-Barroso+, 2017)J/A+A/598/A32 : 2D decomposition of CALIFA galaxies (Mendez-Abreu+, 2017)J/A+A/604/A4 : CALIFA galaxies observational hints (Ruiz-Lara+, 2017)J/ApJ/826/71 : Growth curves of CALIFA spiral galaxieshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/609/A102https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/609/A102http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/609/A102https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/609/A102https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/609/A102http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/609/A102GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/609/A102/table4 (Physical properties for 263 galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/609/A102/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/609/A102/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/609/A102/table4?GETtext/xml+votable180.050000true23.323612513.33243610.0055555555555555566/56 554 568 573 721 733 738 909 995 2206 2229 2248 2251 2272-2274 2290 2641 4053 4178 4445 4454 4507 4511 4799 4813 4843 4950 5247 5298 5332 5505 5533 5579 5593 5701 5704 6214 6216 6240 6270 6342 6362 6366 6977 7204 7214 7309 7340 7501 7559 7584 7591 7824 7834 7844 8045 8327 8331 8366 8458 8480 8492 8498 8522 8536 8552 8562-8563 8646 8728 8743 8752 8825 8883 8919 8921-8922 9098 9101 9124 9133 9187 9216 9220 9622 9628 9718 9798 9859 9875 9883 9885 9891 9974 10025 10111 10113 10183 10200 10220-10221 10280 10286 10380 10398 10414 10422 10434 10448 10485 10511 10518 10524 10566 10570 10577 10588 10595 10612 10621 10627-10629 10661-10662 10674 10705 10711 10721 10727 10739-10740 10778 10846 10987 11112 11196 11272 11290 11342 11372 11374 11377 11383 11392 11396 11433 11451 11777 11789 11793 11800 11804 11832 11944 12378 13316 13381 13426 15004 16007 16696 16702 16787 16793 17234 17238 17350 17392 17398 17486 17499 17509 17578 17751 18069 18081 18173 18252 18300 18302 18381 18383 18775 18779 18781 18838 18854 18932 18935 18941 19073 19108 19186 19227 19260 19267 19489 19508 19515 19537 19589 19618 19749 19848 19939 19954 19983 19991 19996 20009 20020 20031 20033 20040 20193 20254 20279 20417-20418 20429 22652 22741 23337 23353 23401 23405 27133 27559 27567 27719 27748 28458 28513 28579 28639 29973 31478 31546 31628 31642 31688-31689 31736 32462 32478 32482 32559 48880 49121 491502.85864675833786e-19 4.653515163505597e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/609/A102?format=asciiOpticaldefaultJ/A+A/609/A102/table4Physical properties for 263 galaxieszRedshiftsrc.redshiftfloatMtypeMorphological typesrc.morph.typecharInclInclinationsrc.orbital.inclinationfloatDistDistanceMpcpos.distancefloatrecnoRecord number assigned by the VizieR team.
