The VPM search is demonstrated to be powerful technique for efficiently finding QSOs without major selection effects with regard to the spectral energy distribution. Remarkably, the properties of the VPM QSOs do not significantly differ from those of samples from more conventional optical search techniques. The lightcurves of the QSOs from the resulting sample provide an interesting data set for the statistical investigation of QSO long-term variability.2002A&A...392..851Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/392/851CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/392/851https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/392/851http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/392/851https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/392/851https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/392/851http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/392/851GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/392/851/table3 (QSOs/Sey1s/NELGs from follow-up spectroscopy of VPM sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/392/851/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/392/851/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/392/851/table3?GETtext/xml+votable180.050000true203.81062529.74869440.005555555555555556Cone search capability for table J/A+A/392/851/table4 (QSOs/Sey1s/NELGs from the NED)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/392/851/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/392/851/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/392/851/table4?GETtext/xml+votable180.050000true203.7992527.94769440.0055555555555555565/2573 2578 2584 6/10271 10318 10340 10342 10344-10345https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/392/851?format=asciiOpticaldefaultJ/A+A/392/851/table3QSOs/Sey1s/NELGs from follow-up spectroscopy of VPM sourcesrecnoRecord number assigned by the VizieR team.
