We use a procedure that uniformly estimates fundamental stellar properties of Tycho 2 stars, with errors, using spline functions of broadband photometry and proper motion found in Hipparcos/Tycho 2 and 2MASS. We provide estimates of effective temperature and distance for 2.4 million Tycho 2 stars that lack trigonometric distances. For stars that appear to be FGK dwarfs, we also derive [Fe/H] and identify unresolved binary systems with mass ratios 1.25<M1/M2<3.0. For FGK dwarfs with photometric error {sigma}_V_<0.05, or V<9, our temperature model gives a 1{sigma} error of {sigma}_T_=+58.7/-65.9K and our metallicity model gives a 1{sigma} error of {sigma}_[Fe/H]_=+0.13/-0.14dex. The binarity model can be used to remove 70% of doubles with 1.25<M1/M2<3.0 from a magnitude-limited sample of dwarfs at a cost of cutting 20% of the sample. Our estimates of distance and spectral type enable us to isolate 354,822 Tycho 2 dwarfs, 321,996 absent from Hipparcos, with giant contamination of 2.6% and 7.2%, respectively. Roughly 100,000 of these stars, not in Hipparcos, have sufficiently low photometric errors to retain 0.13-0.3dex [Fe/H] accuracy and 80-100K temperature accuracy (1{sigma}). Our metallicity estimates have been used to identify targets for N2K, a large-scale radial velocity search for hot jupiters, which has verified the errors presented here. The catalogs that we publish can be used to further large-scale studies of Galactic structure and chemical evolution and to provide potential reference stars for narrow-angle astrometry programs such as the Space Interferometry Mission and large-aperture optical interferometry.2006ApJ...638.1004Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/V/136CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/239 : The Hipparcos and Tycho Catalogues (ESA 1997)I/259 : The Tycho-2 Catalogue (Hog+ 2000)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)http://www.ucolick.org/~ammons/tycho_parameters : Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=V/136https://vizier.iucaa.in/viz-bin/VizieR-2?-source=V/136http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=V/136https://vizier.cds.unistra.fr/viz-bin/votable?-source=V/136https://vizier.iucaa.in/viz-bin/votable?-source=V/136http://vizieridia.saao.ac.za/viz-bin/votable?-source=V/136GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table V/136/tycall (Photometry and derived parameters for all Tycho 2 stars, including giants)https://vizier.cds.unistra.fr/viz-bin/conesearch/V/136/tycall?https://vizier.iucaa.in/viz-bin/conesearch/V/136/tycall?http://vizieridia.saao.ac.za/viz-bin/conesearch/V/136/tycall?GETtext/xml+votable180.050000true0.002811.247301940.005555555555555556Cone search capability for table V/136/tycdwarf (Photometry and derived parameters for dwarfs)https://vizier.cds.unistra.fr/viz-bin/conesearch/V/136/tycdwarf?https://vizier.iucaa.in/viz-bin/conesearch/V/136/tycdwarf?http://vizieridia.saao.ac.za/viz-bin/conesearch/V/136/tycdwarf?GETtext/xml+votable180.050000true0.016593897.513843890.0055555555555555560/0 1 2 3 4 5 6 7 8 9 10 1/46 47 2/178 179 181 182 183 3/706 721 722 723 4/2818 2819 2828 2830 2831 2842 2847 2883 5/11264 11266 11267 11290 11316 11318 11319 11362 11374 11375 11383 11387 11527 11531 6/45062 45063 45080 45082 45083 45154 45155 45164 45166 45167 45178 45268 45270 45271 45442 45454 45455 45488 45490 45491 45494 45525 45526 45527 45530 45531 45541 45542 45543 45545 45546 45547 46102 46103 46105 46106 46107 46117 46118 46119 46121 46122 461233.322582951404819e-19 5.101838343667421e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/V/136?format=asciiOpticaldefaultV/136/tycallPhotometry and derived parameters for all Tycho 2 stars, including giantsrecnoRecord number assigned by the VizieR team.
