cds-question@unistra.freffective-temperaturevisible-astronomytrigonometric-parallaxinfrared-photometryWide-band photometrywhite-dwarf-starsstellar-distanceUsing recent photometric calibrations, we develop greatly improved distance estimates for DA white dwarfs using multi-band synthetic photometry based on spectroscopic temperatures and gravities. Very good correlations are shown to exist between our spectroscopically based photometric distance estimates and those derived from trigonometric parallaxes. We investigate the uncertainties involved in our distance estimates, as well as discuss the circumstances where such techniques are most likely to fail. We apply our techniques to the large sample of Sloan Digital Sky Survey DA white dwarfs where automated fitting of HI Balmer profiles yields spectrometric temperatures and gravities. We determine simple empirical corrections to these temperatures and gravities with respect to published slit spectroscopy. After applying these T_eff_-logg corrections as well as appropriate interstellar extinction corrections, where necessary, we derive spectroscopically based photometric distances for 7062 DA stars from this sample.2008AJ....135.1239Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/135/1239CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/654/499 : H-rich white dwarfs spectropolarimetric survey (Kawka+, 2007)J/A+A/466/627 : Parameters of DA white dwarfs in SDSS-DR1 (Hu+, 2007)J/ApJS/167/40 : SDSS4 confirmed white dwarfs catalog (Eisenstein+, 2006)J/AJ/132/1221 : VJHK and SDSS photometry of DA white dwarfs (Holberg+, 2006)J/ApJ/643/402 : Cool white dwarfs in the solar neighborhood (Kawka+, 2006)J/ApJS/156/47 : DA white dwarfs from the Palomar Green Survey (Liebert+, 2005)J/ApJ/607/426 : Catalog of white dwarfs in SDSS-DR1 (Kleinman+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/135/1239https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/135/1239http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/135/1239https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/135/1239https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/135/1239http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/135/1239GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/135/1239/table1 (Trigonometric parallaxes)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/135/1239/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/135/1239/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/135/1239/table1?GETtext/xml+votable180.050000true3.4130.32358330.005555555555555556Cone search capability for table J/AJ/135/1239/UBVRI (UBVRI photometry and distances)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/135/1239/UBVRI?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/135/1239/UBVRI?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/135/1239/UBVRI?GETtext/xml+votable180.050000true32.836416739.92280560.005555555555555556Cone search capability for table J/AJ/135/1239/ugriz (ugriz photometry and distances)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/135/1239/ugriz?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/135/1239/ugriz?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/135/1239/ugriz?GETtext/xml+votable180.050000true3.4130.32358330.005555555555555556Cone search capability for table J/AJ/135/1239/table7 (SDSS autofit versus slit spectroscopic parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/135/1239/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/135/1239/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/135/1239/table7?GETtext/xml+votable180.050000true3.4130.32358330.0055555555555555566/1890 2366 4162 4566 4795 4947 5050 5068 5096 5674 5816 5826 5827 5871 5872 5893 5898 5927 5941 5972 5989 6081 6118 6442 6454 6541 7212 7478 7498 8250 8516 8894 9071 9109 9158 9165 9383 9391 9424 9468 9506 9751 9832 9840 9966 9981 9985 10194 10378 10386 10504 10525 10647 10675 10680 10966 11095 11127 11159 11178 11193 11336 11374 11399 11415 11835 11875 11984 13391 14865 17577 17879 18068 18086 18410 18902 19428 20155 22709 23187 23194 23198 25938 25943 26012 26188 26212 26221 26297 26321 26386 26471 26916 27223 27236 27333 27432 27490 27524 27538 27930 27934 28271 28460 28559 28574 30754 31390 31405 31637 31677 31698 32436 33015 36730 40070 42760 43537 45110 479572.040811542443644e-19 6.090060298487514e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/135/1239?format=asciiOpticalInfrareddefaultJ/AJ/135/1239/table1Trigonometric parallaxesrecnoRecord number assigned by the VizieR team.
