cds-question@unistra.frsurveyswhite-dwarf-starsproper-motionsphotometryThe GSC-II white dwarf survey was designed to identify faint and high proper motion objects, which we used to define a new and independent sample of cool white dwarfs. With this survey we aim to derive new constraints on the halo white dwarf space density. Also, these data can provide information on the age of thick disk and halo through the analysis of the luminosity function. On the basis of astrometric and photometric parameters, we selected candidates with mu>0.28mas/yr and RF>16 in an area of 1150 square degrees. Then, we separated white dwarfs from late type dwarfs and subdwarfs by means of the reduced proper motion diagram. Finally, spectroscopic follow-up observations were carried out to confirm the white dwarf nature of the selected candidates. We found 41 white dwarfs of which 24 are new discoveries. Here we present the full sample and for each object provide positions, absolute proper motions, photometry, and spectroscopy.2006A&A...448..579Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/448/579CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/128/1825 : Photometry identification of cool white dwarfs (Kilic+, 2004)J/ApJ/582/1011 : Revised NLTT Catalog (Salim+, 2003)J/ApJ/586/1356 : JHKs photometry of 2MASS white dwarf (Wachter+, 2003)J/A+A/363/1040 : DB white dwarfs from the Hamburg/ESO survey (Friedrich+, 2000)J/ApJS/133/413 : BVRIJHK photometry of cool white dwarfs (Bergeron+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/448/579https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/448/579http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/448/579https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/448/579https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/448/579http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/448/579GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/448/579/wd (All parameters of the 41 white dwarfs (tables 2, 3 and 4 of the paper, with improved J2000 positions))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/448/579/wd?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/448/579/wd?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/448/579/wd?GETtext/xml+votable180.050000true8.041-2.90044440.0055555555555555566/218 223 252 7015 8467 10378 10391-10392 10432 10459 10668 10672 10770 10879 10902 10905 10951 11014 11671 17967 18079 18655 18748 18795 18800 19402 19644 19827 26026-26027 26031 26369 26962 28021 28501 28553 31116 316638.650015785639275e-20 6.090060298487514e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/448/579?format=asciiOpticaldefaultJ/A+A/448/579/wdAll parameters of the 41 white dwarfs (tables 2, 3 and 4 of the paper, with improved J2000 positions)NameWD ID in other cataloguesmeta.idcharSpTypeSpectral typesrc.spTypecharrecnoRecord number assigned by the VizieR team.
