cds-question@unistra.frseyfert-galaxiesvery-long-baseline-interferometryradio-continuum-emissionWe have obtained mas-scale resolution very long baseline interferometry (VLBI) images of a sample of Seyfert 1 and Seyfert 2 galaxies at 5GHz (wavelength, {lambda}=6cm). The Seyferts of the two types were chosen to be matched in several orientation-independent properties, primarily in order to rigorously test predictions of the unified scheme. We detected all the 15 objects that we observed. In this paper we describe the observations and data reduction procedures, and present the VLBI radio images as well as simultaneous Very Large Array images that we obtained for these 15 Seyferts.2004A&A...425...99Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/425/99CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/173 : Catalogue of Seyfert Galaxies (Lipovetsky+, 1988)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/425/99https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/425/99http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/425/99https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/425/99https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/425/99http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/425/99GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/425/99/table5 (The VLBI results for Seyfert galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/425/99/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/425/99/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/425/99/table5?GETtext/xml+votable180.050000true19.030083333.08933330.005555555555555556Cone search capability for table J/A+A/425/99/table6 (VLA observational results)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/425/99/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/425/99/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/425/99/table6?GETtext/xml+votable180.050000true19.030037533.089350.0055555555555555566/1405 2229 4992 7132 7214 7741 9882 11416 13414 18794 18897 19283 19376 19619 28517https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/425/99?format=asciiRadiodefaultJ/A+A/425/99/table5The VLBI results for Seyfert galaxiesrecnoRecord number assigned by the VizieR team.
