UBVRI photometry of NLTT stars J/AJ/98/1693 ivo://CDS.VizieR/J/AJ/98/1693 doi:10.26093/cds/vizier.50981693 CDS Ryan S.G. 2017-09-05T09:24:25Z 2017-09-04T11:30:58Z CDS support team CDS, Observatoire de Strasbourg, 11 rue de l'Universite, F-67000 Strasbourg, France cds-question@unistra.fr infrared-photometry visible-astronomy Wide-band photometry subdwarf-stars high-velocity-stars UBVRI photometry is presented for a sample of 1656 southern stars, including 1211, that were previously not measured, drawn from the NLTT (Luyten, 1979; catalogue I/98) proper-motion catalog; the catalog is shown to be a rich source of subdwarfs. The normalized UV excess, d(U-B)0.6, photometric parallax, and interstellar reddening are calculated for each star when possible. Residuals between the photometry and the magnitudes published in the NLTT catalog indicate that the latter have a large scatter (~0.6mag) and therefore the values tabulated in the NLTT catalog must be regarded as approximate only. The erratum (Astron. J. 99, 1336) which deals with position angles of proper motions (pmPA) has been taken into account. 1989AJ.....98.1693R https://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/98/1693 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to I/98 : Luyten's NLTT Catalog https://cds.unistra.fr/vizier-org/licences_vizier.html https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/98/1693 https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/98/1693 http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/98/1693 https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/98/1693 https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/98/1693 http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/98/1693 GET text/xml+votable https://tapvizier.cds.unistra.fr/TAPVizieR/tap Cone search capability for table J/AJ/98/1693/table3 (Observed photometry and derived parameters) https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/98/1693/table3? https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/98/1693/table3? http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/98/1693/table3?
