cds-question@unistra.frwhite-dwarf-starsvisible-astronomysloan-photometryproper-motionsA 2.5x100{deg}^2^ region along the celestial equator (Stripe 82) has been imaged repeatedly from 1998 to 2005 by the Sloan Digital Sky Survey (SDSS). A new catalogue of ~4 million light-motion curves, together with over 200 derived statistical quantities, for objects in Stripe 82 brighter than r~21.5 has been constructed by combining these data by Bramich et al. (2008MNRAS.386..887B). This catalogue is at present the deepest catalogue of its kind. Extracting ~130000 objects with highest signal-to-noise ratio proper motions, we build a reduced proper motion diagram to illustrate the scientific promise of the catalogue. In this diagram, disc and halo subdwarfs are well-separated from the cool white dwarf sequence. Our sample of 1049 cool white dwarf candidates includes at least eight and possibly 21 new ultracool H-rich white dwarfs (Teff<4000K) and one new ultracool He-rich white dwarf candidate identified from their SDSS optical and UKIDSS infrared photometry. At least 10 new halo white dwarfs are also identified from their kinematics.2007MNRAS.382..515Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/382/515CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/282 : The SDSS Photometric Catalog, Release 6 (Adelman-McCarthy+, 2007)http://www.sdss.org : SDSS Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/382/515https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/382/515http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/382/515https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/382/515https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/382/515http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/382/515GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/382/515/WD (Properties of the dwarf candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/382/515/WD?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/382/515/WD?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/382/515/WD?GETtext/xml+votable180.050000true2.7815417-0.51744440.0055555555555555566/17746-17748 17807 17811 17814 17837 18003 18020 18022 18024 18069-18070 18073 18078 18083 18091 18093 18098 18177 18766-18767 18771 18774 18779 18791 18795 18830 18833 18850 18856 18859-18860 18864 18880 19045 19051 19087 19095-19096 19101 19109 19113 19200 19457 23208 30038 30044 30046 368632.040811542443644e-19 4.653515163505597e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/382/515?format=asciiOpticaldefaultJ/MNRAS/382/515/WDProperties of the dwarf candidatesf_SDSSJ[*] Not fully confirmed halo WD candidate (1)meta.codecharn_SDSSJNote on SDSSJ, in notes.dat filemeta.notechargmagSDSS g magnitude in AB systemmagphot.mag;em.opt.Bfloate_gmagrms uncertainty on gmagmagstat.error;phot.mag;em.opt.BfloatrmagSDSS r magnitude in AB systemmagphot.mag;em.opt.Rfloate_rmagrms uncertainty on rmagmagstat.error;phot.mag;em.opt.RfloatimagSDSS i magnitude in AB systemmagphot.mag;em.opt.Ifloate_imagrms uncertainty on imagmagstat.error;phot.mag;em.opt.IfloatzmagSDSS z magnitude in AB systemmagphot.mag;em.opt.Ifloate_zmagrms uncertainty on zmagmagstat.error;phot.mag;em.opt.IfloatJmag?
