cds-question@unistra.frbl-lacertae-objectsradio-galaxiesspectroscopyDirect imaging and spectroscopic data are reported for the complete sample of 34 BL Lac objects selected from the 1Jy source catalogue (see Cat. <VIII/5>). A short description of each individual object is given along with a general discussion of the features observed in the optical spectra, the optical morphologies, and the environments of the BL Lac objects.1993A&AS...98..393Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/98/393CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/5 : Bright Extragalactic Radio Sources (1Jy) (Kuehr+, 1981)III/175 : Optical spectroscopy of radio sources (Stickel+, 1989-94)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/98/393https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/98/393http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/98/393https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/98/393https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/98/393http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/98/393GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+AS/98/393/table1 (Basic data for the 1Jy BL Lac objects)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/98/393/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/98/393/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/98/393/table1?GETtext/xml+votable180.050000true12.6721903-9.48485450.005555555555555556Cone search capability for table J/A+AS/98/393/table7 (Associations of BL Lac objects with clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/98/393/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/98/393/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/98/393/table7?GETtext/xml+votable180.050000true67.1892-38.10770.0055555555555555566/579 4054 4513 4691 4695 4770 4776 4805 6490 6507 7296 7570-7571 7896 8487 9612-9613 9620 10378 10397 10420 10422 11404 11430 11615 11639 11740 13914 13927 15153 15286 16059 16281 16283 16298 17516 17579 19088 19271 19280 21968 24608 28276 28451 28454-28455 31894 34123 34535 34572 35786 44147 44247 47057 47375 47377 473863.313034785154005e-24 3.313034785154005e-24https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+AS/98/393?format=asciiOpticalRadiodefaultJ/A+AS/98/393/table1Basic data for the 1Jy BL Lac objectsrecnoRecord number assigned by the VizieR team.
