cds-question@unistra.fractive-galactic-nucleigalaxiesvisible-astronomypolarimetryWe quantify the temporal behaviour of the optical polarisation fraction and angle for a selected sample of radio-loud NLSy1s. We also search for rotations of the polarisation plane similar to those commonly observed in blazars. The dataset was obtained with the RoboPol polarimeter of the Skinakas observatory as well as the KANATA, Perkins, and Steward observatories. We carried out numerical simulations to assess the probability that long rotations of the polarisation plane were caused by intrinsically evolving electric vector position angles (EVPAs) instead of observational noise. We conclude that it is much more likely that intrinsic rotations are responsible for the observed phenomenology.2018A&A...618A..92Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/618/A92CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/618/A92https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/618/A92http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/618/A92https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/618/A92https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/618/A92http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/618/A92GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/618/A92/sources (List of studied sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/618/A92/sources?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/618/A92/sources?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/618/A92/sources?GETtext/xml+votable180.050000true51.1715041734.179405560.0055555555555555566/893 7226 8199 9245 9470 9754 10020 10181 11065 27243https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/618/A92?format=asciiOpticaldefaultJ/A+A/618/A92/sourcesList of studied sourceszRedshiftsrc.redshiftdoublerecnoRecord number assigned by the VizieR team.
