NExScI Science Data Archives

  • The NASA Exoplanet Archive
    The NASA Exoplanet Archive serves the user community working with exoplanet data, primarily transit data sets from Kepler and CoRoT, by providing long-term data curation and analysis tools.

  • The Keck Observatory Archive (KOA)
    The W. M. Keck Observatory Archive (KOA) serves raw (level 0) science and calibration data acquired with all eight active instruments and two decommissioned instruments. The archive serves all data acquired since the Observatory saw first light in 1994, and newly acquired data are ingested nightly. KOA serves calibrated (level 1) browse products for the HIRES, NIRC2, OSIRIS and LWS instruments. KOA is a collaboration between NASA, NExScI, and the W. M. Keck Observatory.

  • Keck Interferometer data archive
    Data from the Keck Interferometer are available via the Keck Observatory Archive. KI data format and calibration package instructions are available on the KI Support Page.

  • The Palomar Testbed Interferometer (PTI) archive
    The PTI was built as a testbed for the Keck Interferometer but has also been operational as a science instrument since 1997. Data from over 1000 astronomical sources and supporting information are available for download here.

NExScI Software Tools

The NASA Exoplanet Science Institute (NExScI) provides software tools for use in the observation planning and data reduction for supported missions and facilties. This software was developed for direct support of the Keck Interferometer (KI) and Palomar Testbed Interferometer (PTI) however it might also be useful to other investigators.
