cds-question@unistra.frgiant-starsstellar-distanceextinctionWe present a first determination of distances and extinctions for individual stars in the first release of the APOKASC catalogue, built from the joint efforts of the Apache Point Observatory Galactic Evolution Experiment (APOGEE) and the Kepler Asteroseismic Science Consortium (KASC). Our method takes into account the spectroscopic constraints derived from the APOGEE Stellar Parameters and Chemical Abundances Pipeline, together with the asteroseismic parameters from KASC. These parameters are then employed to estimate intrinsic stellar properties, including absolute magnitudes, using the Bayesian tool param. We then find the distance and extinction that best fit the observed photometry in Sloan Digital Sky Survey (SDSS), 2MASS, and WISE passbands. The first 1989 giants targetted by APOKASC are found at typical distances between 0.5 and 5kpc, with individual uncertainties of just ~1.8%. Our extinction estimates are systematically smaller than provided in the Kepler Input Catalogue and by the Schlegel et al. maps. Distances to individual stars in the NGC 6791 and NGC 6819 star clusters agree to within their credible intervals. Comparison with the APOGEE red clump and SAGA catalogues provide another useful check, exhibiting agreement with our measurements to within a few per cent. Overall, present methods seem to provide excellent distance and extinction determinations for the bulk of the APOKASC sample. Approximately one third of the stars present broad or multiple-peaked probability density functions and hence increased uncertainties. Uncertainties are expected to be reduced in future releases of the catalogue, when a larger fraction of the stars will have seismically determined evolutionary status classifications.2014MNRAS.445.2758Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/445/2758CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)V/133 : Kepler Input Catalog (Kepler Mission Team, 2009)II/311 : WISE All-Sky Data Release (Cutri+ 2012)J/ApJS/199/30 : Effective temperature scale for KIC stars (Pinsonneault+, 2012)J/ApJS/211/2 : Q1-16 Kepler targets revised stellar properties (Huber+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/445/2758https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/445/2758http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/445/2758https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/445/2758https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/445/2758http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/445/2758GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/445/2758/table1 (Derived distances and extinctions with the Bayesian and direct methods for APOKASC stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/445/2758/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/445/2758/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/445/2758/table1?GETtext/xml+votable180.050000true291.3599936.819888890.0055555555555555565/3645-3646 3688 3695 3706 3730-3731 3736-3737 3740-3742 3779-3782 3784-3785 3787 3792 6/14567 14573 14575 14578-14579 14588-14589 14730-14731 14760 14767 14775 14777-14779 14818-14819 14822 14828 14830-14831 14914-14916 14918-14919 14937-14940 14942-14943 14952-14953 14956 14972-14974 15109 15111 15114-15115 15132-15134 15144-15145 15147 15154 15160 15172-15174 15176https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/445/2758?format=asciidefaultJ/MNRAS/445/2758/table1Derived distances and extinctions with the Bayesian and direct methods for APOKASC starsrecnoRecord number assigned by the VizieR team.
