cds-question@unistra.frquasarsredshiftedA new low frequency radio selected Sample of 125 Quasars complete down to 100mJy at 408MHz is presented in this paper. The sample is a part of the B3-VLA sample: 1050 radiosources selected from the B3 catalogue at 408MHz and observed at the VLA (1465MHz, C and A configurations). Out of the 352 sources, identified on the POSS-I down to m_r_~20.0, 172 are quasar candidates. In this paper we give the final assessment of the quasar sample from spectroscopic observations of the candidates. The final complete quasar sample consists of 125 objects. Furthermore 3 Bl Lac objects have been identified and two Bl Lac candidates.1997A&AS..123..219Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/123/219CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/37 : The Third Bologna Survey (B3) (Ficarra+ 1985)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/123/219https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/123/219http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/123/219https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/123/219https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/123/219http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/123/219GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+AS/123/219/table4 (The B3-VLA Quasars Complete Sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/123/219/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/123/219/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/123/219/table4?GETtext/xml+votable180.050000true17.685422940.12187820.0055555555555555566/1018 2294 2363 2366 2375 2378 2400 2405 2411 2448 2463-2464 2466 2482 2489 2501 2516 2619 2630 2637 2648 2693-2694 2699 2701 2706 2711 2722 2737 3086 5087 5109 5359 5371 5430 5435 5439 5445 5447-5448 5458 5472 5533 5546 5588 5689 5691 5693 5706 5722 5728 5730 5763 5765 5767 5770-5771 5773 5786 5806 6390 6396 6472 6486 6490 6496 6503 6511 6535-6536 6545-6546 6560 6723 6729 6913 7181 10479 10548 10551 10557 10563 10585 10628-10629 10631 10633-10634 10656 10686 10803 10815 10821 10826-10827 10832 10848-10849 10863 10890 10898 10925 10945 13629 13639 13643-13644 13654 13659 13668 13693 13800 28660 28663 286662.703436334132769e-25 2.703436334132769e-25https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+AS/123/219?format=asciiOpticaldefaultJ/A+AS/123/219/table4The B3-VLA Quasars Complete SampleB3B3 namemeta.id;meta.maincharprimaryrecnoRecord number assigned by the VizieR team.
