Using emission-line ratios, we identify a total of 162 (3%) Seyfert galaxies out of the parent sample with 5399 galaxies. The sample contains 121 Seyfert 2 galaxies and 41 Seyfert 1 galaxies. The SSRS2 Seyfert galaxies are predominantly in spirals of types Sb and earlier or in galaxies with perturbed appearance as the result of strong interactions or mergers. Seyfert galaxies in this sample are twice as common in barred hosts as the non-Seyfert galaxies. By assigning galaxies to groups using a percolation algorithm, we find that the Seyfert galaxies in the SSRS2 are more likely to be found in binary systems when compared with galaxies in the SSRS2 parent sample. However, there is no statistically significant difference between the Seyfert and SSRS2 parent sample when systems with more than two galaxies are considered. The analysis of the present sample suggests that there is a stronger correlation between the presence of the AGN phenomenon with internal properties of galaxies (morphology, presence of bar, luminosity) than with environmental effects (local galaxy density, group velocity dispersion, nearest neighbor distance).</description><source format="bibcode">2003AJ....126.1750M</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/126/1750</referenceURL><type>Catalog</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/TAP">TAP VizieR generic service</relatedResource></relationship><relationship><relationshipType>IsServedBy</relationshipType><relatedResource>Conesearch service</relatedResource></relationship><relationship><relationshipType>related-to</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/J/AJ/116/1">J/AJ/116/1 : Southern Sky Redshift Survey, SSRS2 (Da Costa+, 1998)</relatedResource></relationship></content><rights>https://cds.unistra.fr/vizier-org/licences_vizier.html</rights><capability><interface xsi:type="vr:WebBrowser"><accessURL use="full">https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/126/1750</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/126/1750</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/126/1750</mirrorURL></interface></capability><capability><interface xsi:type="vs:ParamHTTP"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/126/1750</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/126/1750</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/126/1750</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface></capability><capability standardID="ivo://ivoa.net/std/TAP#aux"><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://tapvizier.cds.unistra.fr/TAPVizieR/tap</accessURL></interface></capability><capability xsi:type="cs:ConeSearch" standardID="ivo://ivoa.net/std/ConeSearch"><description>Cone search capability for table J/AJ/126/1750/table1 (SSRS2 Seyfert Galaxies)</description><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/126/1750/table1?</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/126/1750/table1?</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/126/1750/table1?</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface><maxSR>180.0</maxSR><maxRecords>50000</maxRecords><verbosity>true</verbosity><testQuery><ra>0.88375</ra><dec>-10.744722</dec><sr>0.005555555555555556</sr></testQuery></capability><coverage><spatial>6/16533-16534 16690 16702 16740 16748 16765 16784 16800 16868 16877 16936 17061 17111 17134 17173 17213 17241 17273 17369 17392 17441 17492 17495 17513 17525 17582 18052 18484 18507 18524 18592 18714 18742 18762 22692 23075 23086 23171 24699 24829 24885 24896 24916 25051 25053-25054 25083 25182 25263 25476 25497 25509 25518 25572 25610 25647 25661 25742 25782 25790 25890 25907 25992 26121 26128 26148 26181 26651 26683 26729 26743 26808 26835 26854 26860 26866 26899 26910 26920 27160 27186 34499 34531 34534 34558 34576 34578 34695 35263 35284 35300 35447 35537 35613 35623 35638 35717 35719 35744 35850 35899 35983 35993 36005 36020 36023 36062 36081 36132 36158 36171 36198 36207 36216 36457 36618 36647 36668 36671 36678 36716 36733 36763 36775 36785-36786 43983 43995-43996 44005 44017 44023 44028 44660 44696 44757 44812 44892 44960 46452 46513 46525 46544 46709 46715 46811 46977 46987 47027 47047 47064 47093 48233 48516 48605</spatial><footprint ivo-id="ivo://ivoa.net/std/moc">https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/126/1750?format=ascii</footprint><waveband>Optical</waveband></coverage><tableset><schema><name>default</name><table><name>J/AJ/126/1750/table1</name><description>SSRS2 Seyfert Galaxies</description><column><name>recno</name><description>Record number assigned by the VizieR team.
