cds-question@unistra.frradio-sourcesquasarsradio-galaxiesbl-lacertae-objectsspectroscopyredshiftedvery-long-baseline-interferometryIn extending our spectroscopic program, which targets sources drawn from the International Celestial Reference Frame (ICRF) Catalog, we have obtained spectra for ~160 compact, flat-spectrum radio sources and determined redshifts for 112 quasars and radio galaxies. A further 14 sources with featureless spectra have been classified as BL Lac objects. Spectra were obtained at three telescopes: the 3.58m European Southern Observatory New Technology Telescope, and the two 8.2m Gemini telescopes in Hawaii and Chile. While most of the sources are powerful quasars, a significant fraction of radio galaxies is also included from the list of non-defining ICRF radio sources.2017AJ....153..157Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/153/157CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/259 : 6dF galaxy survey final redshift release (Jones+, 2009)I/323 : International Celestial Reference Frame 2, ICRF2 (Ma+, 2009)J/AJ/150/58 : VLBI ICRF2 (Fey+, 2015)J/AJ/146/10 : Spectroscopy of emission-line ICRF2 candidates (Titov+, 2013)J/A+A/559/A95 : Fitted proper motions for the DR solution (Titov+, 2013)J/A+A/529/A91 : Proper motions of 555 quasars from VLBI (Titov+, 2011)J/A+A/506/1477 : Radio source distribution (Titov+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/153/157https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/153/157http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/153/157https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/153/157https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/153/157http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/153/157GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/153/157/table1 (Observed emission lines)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/153/157/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/153/157/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/153/157/table1?GETtext/xml+votable180.050000true1.030239444-43.7528183330.005555555555555556Cone search capability for table J/AJ/153/157/table3 (Objects with low signal-to-noise spectra)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/153/157/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/153/157/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/153/157/table3?GETtext/xml+votable180.050000true1.274687778-34.7637933330.005555555555555556Cone search capability for table J/AJ/153/157/table2 (Probable BL Lac objects)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/153/157/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/153/157/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/153/157/table2?GETtext/xml+votable180.050000true5.385622778-25.8470519440.0055555555555555566/770 904 949 1173 2053 2122 2140 2429 2682 10081 13406 13427 13447 13712 16286 16411 16510 16777 17091 17418 18265 18365 18552 18889 18931 19074 19333 19553 20220 20802 21055 21493 21625 21707 21723 21809 22657 24181 24635 25071 25340 26778 26854 29373 29421 30017 30906 31143 31527 32778 32909 32969 33220 33382 33399 33468 33528 33636 33744 33868 34085 34118 34158 34487 35401 35488 35562 35600 35781 35865 36018 36276 36460 36614 36718 36807 36882 36901 37104 37765 37779 37994 38089 38110 38166 38416 39469 39536 39695 39957 39978 39997 40333 40343 40354 40458 40463 40990 41073 41080 41084 41295 42012 42017 42024 42040 42540 42681 43283 43567 43597 43723 43753 43786 44099 44335 44338 45198 45364 45371 45451 45491 45497 45511 45600 45698 45928 45972 46000 46232 46552 46619 46831 47154 47498 47513 47630 47708 47889 47969 48063 48404 48715 48724 48732 49076https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/153/157?format=asciiRadiodefaultJ/AJ/153/157/sourcesObserved IVS objectsrecnoRecord number assigned by the VizieR team.
