It is based on flux ratios estimates in spectral bands flanking the expected H {alpha} broad component H {alpha}_BC_. The high signal-to-noise ratio obtained (mean S/N = 84) permits the identification of H {alpha}_BC_ without prior subtraction of the host galaxy (HG) stellar component. A final sample of 47 type-1 AGN is reported out of 4700 galaxies at z < 0.15. The results were compared with those from other methods based on the SDSS DR7 and MaNGA data. Detection of type-1 AGN in those works compared to our method goes from 26 per cent to 81 per cent. Spectral indexes were used to classify the type-1 AGN spectra according to different levels of AGN-HG contribution, finding 9 AGN-dominated, 14 intermediate, and 24 HG-dominated objects. Complementary data in NIR-MIR allowed us to identify type I AGN-dominated objects as blue and HG-dominated as red in the WISE colours. From NVSS and FIRST radio continuum data, we identify 5 HERGs (high-excitation radio galaxies) and 4 LERGs (low-excitation radio galaxies), three showing evidence of radio-jets in the FIRST maps. Additional X-ray data from ROSAT allowed us to build [O III] and H {alpha}_BC_ versus X-ray, NIR-MIR, and radio continuum diagrams, showing that L(H {alpha}_BC_) and L([O III]) provide good correlations. The range in H {alpha}_BC_ luminosity is wide 38 < logL(H {alpha}_BC_) < 44, with logFWHM(H {alpha}_BC_) ~ 3-4, covering a range of Eddington ratios of -5.15 < log L_bol_ / L_Edd_ < 0.70. Finally, we also identify and report ten possible changing-look AGN candidates.2022MNRAS.514.3626Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/514/3626CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/234/23 : The WISE AGN candidates catalogs (Assef+, 2018)J/ApJS/221/12 : AGNs in the MIR using AllWISE data (Secrest+, 2015)J/ApJ/901/159 : MaNGA AGNs from WISE, Swift/BAT, NVSS & FIRSTJ/MNRAS/492/4680 : Ionized gas outflow signatures in MaNGA AGNJ/ApJ/804/27 : NIR photometry of hot dust-obscured galaxies (Assef+, 2015)J/ApJS/243/21 : A complete sample of broad-line AGN from SDSS-DR7J/ApJS/219/1 : Catalog of Type-1 AGNs from SDSS-DR7 (Oh+, 2015)J/A+A/588/A103 : Second ROSAT all-sky survey (2RXS) source catalogVIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998)J/ApJS/98/477 : Optical spectral atlas of Seyfert nuclei (Ho+ 1995)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/514/3626https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/514/3626http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/514/3626https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/514/3626https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/514/3626http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/514/3626GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/514/3626/table3 (Physical properties of the 47 type-1 AGN sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/514/3626/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/514/3626/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/514/3626/table3?GETtext/xml+votable180.050000true319.193111.04370.005555555555555556Cone search capability for table J/MNRAS/514/3626/tablea1 (Physical properties of the 236 type-2 AGN sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/514/3626/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/514/3626/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/514/3626/tablea1?GETtext/xml+votable180.050000true232.158142.4420.0055555555555555565/1636 1645 2462 6/555 4661 4704 4718 4726 4784 4819 4822-4824 4830 4850 4858 4902 4908 4920 4923 4992 5030 5118 5349 5360 5362 5470 5532 5534 5551 5554 5558 5563-5564 5566 5579 5594 5600 5613 5615 5618 5620 5638-5639 5713 5748 5751-5752 5800 5808 5889 5918 5922 5929 5955 5957-5959 5970 5979-5980 5989 6209 6212 6215 6220 6223 6236 6243 6245 6249 6264 6385 6391 6399 6438 6447 6458-6459 6523 6532 6534-6535 6541 6559 6567 6569 6584 6588 6599 6602 6605 6637 6643 6648 6740 7184 7186 7309 7314 8693 8890-8891 9058 9068 9070 9111 9161 9251-9252 9264-9265 9272-9273 9279 9363 9367-9368 9462 9468 9470-9471 9474 9480 9484 9504 9513 9520 9604 9607 9612 9638 9641-9642 9644 9787 9807 9828 9836 9839 9852 9854 9883 9909 9912 9928 9937 9956 9986-9987 9990 9993 10027 10074 10085 10104 10112-10113 10182 10188 10192 10200 10202 10246-10247 10256 10262 10269 10271 10289-10290 10292 10350 10379 10391 10399 10437 10442 10456 10460-10461 10487 10621-10622 10657 10670 10673 10675-10676 10691 10695-10696 10706 10725 10746 10869 10911 10932 10941 10950 11019 11040 11042 11269 11312 11321 11348 11381-11382 11388 11406 11587 12391 12398 12408 17756 18779 19087 19090 19097 19100-19101 19385 22718 23049 23101 23194 23204-23205 23208-23209 23216 27314 30040 30044 32509 36861https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/514/3626?format=asciiOpticaldefaultJ/MNRAS/514/3626/table3Physical properties of the 47 type-1 AGN samplerecnoRecord number assigned by the VizieR team.
