The Kepler Science Pipeline provides calibrated pixels, simple and systematic error- corrected aperture photometry, and centroid locations for all 165,000 Long Cadence (LC) target stars sampled at 29.5 min integrations, along with associated uncertainties. Based on the first 44 days of data collected by Kepler, over 700 planetary candidates have been identified by the Science Pipeline. The released Kepler data products are available on the Multimission Archive at STScI (MAST) Kepler website, http://stdatu.stsci.edu/kepler. The Science Operations Center (SOC) Pipeline also searches through all light curves for evidence of periodic transit signals that occur when a planet crosses the disk of its host star. The Data Validation (DV) pipeline component calculates a suite of diagnostic metrics for each transit-like signature discovered, and also extracts planetary and stellar parameters by fitting a limb-darkened transit model to each potential planetary signature. This paper provides an overview of the Kepler Science Pipeline and highlights improvements and extensions available with SOC Build 7.0. These changes will allow TPS to search multiple quarterly segments of data for signatures of transiting planets, and DV to fit limb-darkened transit curves to the light curves identified with transit-like features across the entire data set accumulated to date. Additional new diagnostics provided for each candidate will include pixel-based metrics to assist with identifying background eclipsing binaries in an automated fashion. We provide examples of the light curves and other data products provided by the Science Pipeline.
