Abstract

Ten days of commissioning data (Quarter 0) and 33 days of science data (Quarter 1) yield instrumental flux time series of~ 150,000 stars that were combed for transit events, termed threshold crossing events (TCE), each having a total detection statistic above 7.1 σ. TCE light curves are modeled as star+ planet systems. Those returning a companion radius smaller than 2R J are assigned a Kepler Object of Interest (KOI) number. The raw flux, pixel flux, and flux-weighted centroids of every KOI are scrutinized to assess the likelihood of ...
