cds-question@unistra.frbl-lacertae-objectssurveysx-ray-sourcesradio-sourcesredshiftedThe multi-frequency sedentary survey is a flux-limited, statistically well-defined sample of highly X-ray dominated (i.e., with a very high X-ray to radio flux ratio) BL Lacertae objects, which includes 150 sources. In this paper, the third of the series, we report the results of a dedicated optical spectroscopy campaign that, together with results from other independent optical follow-up programs, led to the spectroscopic identification of all sources in the sample. We carried out a systematic spectroscopic campaign for the observation of all unidentified objects of the sample using the ESO 3.6m, the KPNO 4m, and the TNG optical telescopes.2007A&A...470..787Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/470/787CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/434/385 : X-ray/radio data of high energy peaked BL Lacs (Giommi+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/470/787https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/470/787http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/470/787https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/470/787https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/470/787http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/470/787GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/470/787/table3 (Positional information)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/470/787/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/470/787/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/470/787/table3?GETtext/xml+votable180.050000true3.86791735.6113890.005555555555555556Cone search capability for table J/A+A/470/787/table6 (*Featureless sedentary HBL)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/470/787/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/470/787/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/470/787/table6?GETtext/xml+votable180.050000true3.8662535.61083330.0055555555555555566/29 70 2249 2295 2610 4160 4748 6223 7641 8008 8595 8714 8762 9168 9455 9694 10071 10572 10756 10791 12433 13613 14985 16015 16614 16796 17146 17161 17519 17775 18498 18513 19786 20438 20456 20546 20696 21028 22608 22947 23516 24744 25061 25068 25203 25209 25582 26590 27145 27165 27217 30035 30772 30954 31015 34420 34617 34721 34771 35311 35630 35817 36005 36028 36033 36117 36232 38797 38868 43421 43630 43634 43679 44563 44813 44820 45016 45038 46542 46924 47043 48253 48284 48316 48419 48443 48477 48985https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/470/787?format=asciiX-rayOpticalRadiodefaultJ/A+A/470/787/table3Positional informationrecnoRecord number assigned by the VizieR team.
