Scientific paper

The initial estimates of the intrinsic exoplanet frequencies were based on the first 132 days of Kepler observations and on the stellar properties listed in the Kepler Input Catalog (KIC). Improved estimates of stellar temperatures, sizes, and metallicities are being obtained from spectroscopic observations of individual target stars and SME analysis. In turn, the new values of stellar properties contribute to more accurate estimates of candidate size and association with stellar characteristics. Continued analysis of the candidates has increased the certainty for separating false positives from true candidates. Based on the improved candidate and stellar parameter values, we present updated and extended estimates of intrinsic frequencies and the associations of exoplanets with stellar parameters.
