Kepler Guest Observer Program

Kepler Public Data

All Kepler data are released to the entire astronomical community for further analysis. NASA provides financial support for downstream analysis of data collected by its missions, via the Astrophysical Data Analysis program, a yearly solicitation with a submission deadline in mid-May (13 May for 2011).

Kepler Public Data consists of eight components:

  1. Releases of all time series data collected for an entire observing quarter, as described in this schedule.

  2. Sources which were dropped from the exoplanet survey, after analysis of their suitability for detection of transits produced by Earth-sized planets. Dropped targets are listed at the Kepler Archive. A significant number of Quarter 3 light curves are available as dropped targets.

  3. Light curves released whenever a paper discussing the data is published by the Science Team in the peer-reviewed literature. The Kepler archive at MAST maintains a list of published data with links directly to the source information and associated data sets.

  4. Data obtained as part of the Guest Observer Program. These data are released after a proprietary period, as described in this schedule, or released when published in the literature.

  5. Data released directly by the Guest Observer Office. An example of the latter is the short cadence Q6 light curve for the brightest star in the Kepler field, θ Cygni. The target pixel data for this star can be obtained from MAST using KepID = 100002733.

  6. Light curves obtained by the Kepler Asteroseismic Science Consortium (KASC), under agreement with the Kepler project, to probe the interiors of stars using the techniques of asteroseismology.

  7. Light curves obtained for stars in four open clusters of different ages located within the Kepler field. The "Stellar Cluster Project" is a special component of the Science Program. Data is released one year after archiving, and can be identified on the Kepler Data Search and Retrieval page, using the investigation ID = STC.

  8. Images of the entire field-of-view, obtained each month, and released immediately after calibration. Details on the format, content, and utility of these full-frame images (FFIs) can be found here; the images themselves can be obtained from the MAST FFI page.

KASC targets can be identified by using these identifiers within the investigation ID field: STKL and STKS, for long and short cadence data respectively.
