Data Archive

Kepler data for all the stars are processed at NASA Ames Research Center. Processing includes calibrating, removing bias (dark level) and smear (the photometer has no shutter) and converting values 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. Ensemble-normalized light curves are produced and placed in archives (MAST and NExA).

The Mikulski Archive for Space Telescopes (MAST)

at Space Telescope Science Institute (STScI) has the processed data delivered from the Kepler Mission, archived at The public Kepler Planet Candidates are there as well.

The Kepler Kepler and K2 Science Center website has:

The NASA Exoplanet Archive (NExA)

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 NExA you will find:

See instructions for Getting Kepler Light Curves.

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.

At the end of the mission, final processing of data for the whole mission and light curves for all of the stars for the full duration of the mission is added to the archive. Light curves have included differential ensemble normalization. The Kepler archive in MAST is expected to be supported for ten years after the end of mission.

[Older tool: The Kepler Candidate Planet Data Explorer has an interactive table and graph plotting functions, but data has not been updated since 2011.]
