We present a first determination of distances and extinctions for individualstars in the first release of the APOKASC catalogue, built from the jointefforts of the Apache Point Observatory Galactic Evolution Experiment (APOGEE)and the Kepler Asteroseismic Science Consortium (KASC). Our method takes intoaccount the spectroscopic constraints derived from the APOGEE StellarParameters and Chemical Abundances Pipeline, together with the asteroseismicparameters from KASC. These parameters are then employed to estimate intrinsicstellar properties, including absolute magnitudes, using the Bayesian toolPARAM. We then find the distance and extinction that best fit the observedphotometry in SDSS, 2MASS, and WISE passbands. The first 1989 giants targetedby APOKASC are found at typical distances between 0.5 and 5 kpc, withindividual uncertainties of just ~1.8 per cent. Our extinction estimates aresystematically smaller than provided in the Kepler Input Catalogue and by theSchlegel, Finkbeiner and Davis maps. Distances to individual stars in the NGC6791 and NGC 6819 star clusters agree to within their credible intervals.Comparison with the APOGEE red clump and SAGA catalogues provide another usefulcheck, exhibiting agreement with our measurements to within a few percent.Overall, present methods seem to provide excellent distance and extinctiondeterminations for the bulk of the APOKASC sample. Approximately one third ofthe stars present broad or multiple-peaked probability density functions andhence increased uncertainties. Uncertainties are expected to be reduced infuture releases of the catalogue, when a larger fraction of the stars will haveseismically-determined evolutionary status classifications.
