cds-question@unistra.frpeculiar-variable-starsmagnetic-fieldsWe have investigated a sample of 28 well-known spectroscopically-identified magnetic Ap/Bp stars, with weak, poorly-determined or previously undetected magnetic fields. The aim of this study is to explore the weak part of the magnetic field distribution of Ap/Bp stars. Using the MuSiCoS and NARVAL spectropolarimeters at Telescope Bernard Lyot (Observatoire du Pic du Midi, France) and the cross-correlation technique Least Squares Deconvolution (LSD), we have obtained 282 LSD Stokes $V$ signatures of our 28 sample stars, in order to detect the magnetic field and to infer its longitudinal component with high precision (median sigma=40G).2007A&A...475.1053Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/475/1053CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/162 : General Catalogue of Ap and Am stars (Renson+ 1991)J/A+A/407/631 : Catalogue of stellar effective magnetic fields (Bychkov+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/475/1053https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/475/1053http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/475/1053https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/475/1053https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/475/1053http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/475/1053GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/475/1053/stars (Star positions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/475/1053/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/475/1053/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/475/1053/stars?GETtext/xml+votable180.050000true21.077813143.14209670.0055555555555555566/351 481 962 2818 3571 3678 3694 5501 6229 7527 14513 14567 15424 18797 22849 23744 23782 23945 24108 26691 27541 28137 30438 31511 31716 36563 40882https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/475/1053?format=asciidefaultJ/A+A/475/1053/starsStar positionsrecnoRecord number assigned by the VizieR team.
