cds-question@unistra.frseyfert-galaxiesgalaxiesradio-astronomyWe have used the Very Large Array (VLA) to conduct a survey for radio continuum emission in the sample of 52 Seyfert nuclei selected from the optical spectroscopic galaxy catalog of Ho, Filippenko, & Sargent (1995, Cat. <J/ApJS/98/477>. This Seyfert sample is the most complete and least biased available, and, as such, it will be useful for a variety of statistical analyses. Here we present the observations, measurements, and an atlas of radio maps. The observations were made at 6 cm in the B array and at 20 cm in the A array, yielding matched angular resolutions of ~1". We detected 44 objects (85%) at 6 cm and 37 objects (71%) at 20 cm above a 3{sigma} threshold of 0.12mJy/beam. The sources have a wide range of radio powers (P~10^19^-10^25^W/Hz), spectral indices ({alpha}^20^_6_~+0.5 to 1), and linear sizes (L~few tens pc - 15kpc). The morphology of the radio emission is predominantly that of a compact core, either unresolved or slightly resolved, occasionally accompanied by elongated, jetlike features. Linearly polarized emission was detected at 6 cm in 12 sources, nine of which were also detected at 20 cm.2001ApJS..133...77Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/133/77CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/98/477 : Optical spectral atlas of Seyfert nuclei (Ho+ 1995)J/ApJS/112/315 : Spectroscopic parameters of Seyfert nuclei (Ho+ 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/133/77https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/133/77http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/133/77https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/133/77https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/133/77http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/133/77GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/133/77/table1 (The Galaxy Sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/133/77/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/133/77/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/133/77/table1?GETtext/xml+votable180.050000true9.7391666748.337333330.005555555555555556Cone search capability for table J/ApJS/133/77/table3 (Radio Measurements)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/133/77/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/133/77/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/133/77/table3?GETtext/xml+votable180.050000trueCone search capability for table J/ApJS/133/77/table4 (Background Sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/133/77/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/133/77/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/133/77/table4?GETtext/xml+votable180.050000true9.58583348.4727780.0055555555555555566/975 986 1006 1701 2142 2372 2774 2780 4439 4447 5183 5202 5975 7129 7132 7214 7215 7374 7424 7426 7550 7606 7642 7659 8042 8085 8922 8923 10451 10454 10460 10475 10628 10912 10925 10927 10938 10977 10979 10980 11027 11443 15955 17754 18242 19609 19611 20000 22651 22654 23075 26346 26365 27704 27705 27719 27721 27767 27857 27914 27918 27938 27944 27945 28039 28123 28141 28515 28535 28538 28540 28653https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/133/77?format=asciiRadiodefaultJ/ApJS/133/77/table1The Galaxy SamplerecnoRecord number assigned by the VizieR team.
