Data Archive

The data from the Kepler Mission are processed and archived in the Mikulski Archive for Space Telescopes at Space Telescope Science Institute (STScI). The public Kepler Planet Candidates are there as well.

The Kepler Guest Observer website has:

The NASA Exoplanet Science Institute (NExScI) Exoplanet Archive collects and serves public data to support the search for and characterization of all extra-solar planets (exoplanets) and their host stars. The data include published light curves with interactive, multi-quarter visualizer , images, spectra and parameters, and time-series data from surveys that aim to discover transiting exoplanets. Tools, including phasing and periodogram tools, are provided to work with the data, particularly the display and analysis of transit data sets from Kepler and CoRoT. All data are validated by the Exoplanet Archive science staff and traced to their sources.

At NExScI you will find:

The Kepler Candidate Planet Data Explorer has not only an interactive table, but graph plotting functions as well.

The data are calibrated. Bias (dark level) and smear (the photometer has no shutter) is removed and values converted to fluxes. The multiple pixels making up a single star's psf is not combined, permitting users to perform their own photometry or other forms of analysis. In addition, light curves for all the stars are processed on a quarterly basis at NASA Ames Research Center. Ensemble-normalized light curves will be placed in the archive; there may be a quarter year lag for processing. The STScI provides support to the data archive users through the Mikulski Archive for Space Telescopes (MAST). Users are able to search data bases to ascertain what data exists on targets of potential interest, and to determine when specific observations will be available (consistent with proprietary restrictions) for access. Data Archive Program (DAP) users as well as unfunded users have access to data in a convenient form via internet.

After the end of the mission, there will be a final processing to calibrated units using the latest calibration information for the whole mission. The light curves for all of the stars for the full duration of the mission derived by the Kepler science team will also be added to the archive. These curves will have included differential ensemble normalization. The Kepler archive in MAST is expected to be supported for ten years after the end of mission.
