cds-question@unistra.frbl-lacertae-objectspolarimetryWe report on multifrequency linear polarization monitoring of 15 active galactic nuclei containing highly relativistic jets with apparent speeds from ~4c to >40c. The measurements were obtained at optical, 1mm, and 3mm wavelengths, and at 7mm with the Very Long Baseline Array. The data show a wide range in degree of linear polarization among the sources, from <1% to >30%, and interday polarization variability in individual sources. The polarization properties suggest separation of the sample into three groups with low, intermediate, and high variability of polarization in the core at 7mm (LVP, IVP, and HVP, respectively).2007AJ....134..799Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/134/799CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/134/799https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/134/799http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/134/799https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/134/799https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/134/799http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/134/799GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AJ/134/799/table1Optical Polarization DatarecnoRecord number assigned by the VizieR team.
