cds-question@unistra.fro-starspolarimetryPolarimetric data associated with multi-parameter observational campaigns of selected bright O-type stars and their variable winds, are analysed in relation to the outcomes of the UV and optical spectroscopic studies. For the stars {xi} Per and {lambda} Cep, individual measurement uncertainties are {Delta}p~+/-0.0002 with nightly mean uncertainties of {Delta}p~+/-0.00007. Although variability is apparent on a night-to-night basis, with differences in {Delta}p~0.0002, no correlations are found between these and the periodic behaviours associated with the stellar SiIV and H{alpha} lines.2002A&A...383..580Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/383/580CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/116/257 : Variability in O-stars wind (Kaper+, 1996)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/383/580https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/383/580http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/383/580https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/383/580https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/383/580http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/383/580GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/383/580/tablevPolarimetric data (V-band) from the 1991 October campaign for {xi} Per, {lambda} Cep and 68 CygrecnoRecord number assigned by the VizieR team.
