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 8 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.

  • Exoplanet Follow-up Observing Program (ExoFOP)
    The Exoplanet Follow-up Observing Program (ExoFOP) website is designed to optimize resources and facilitate collaboration in follow-up studies of exoplanet candidates. ExoFOP serves as a repository for community-gathered follow-up data by allowing upload and display of data and derived astrophysical parameters.

  • LBTI Data Archive
    The LBTI archive at NExScI contains all NASA data obtained by the Large Binocular Telescope Interferometer, a NASA-funded instrument built and operated by the University of Arizona to study extrasolar planetary systems. Learn more about the LBTI here and explore the LBTI Data Archive.

  • NEID Archive
    NEID is an astronomical spectrograph designed to detect and measure masses of extrasolar planets using the Doppler technique. The instrument was funded by the NASA-NSF Exoplanet Observational Research (NN-EXPLORE) program to be designed and built by the Pennsylvania State University. The NEID Archive is operated by the NExScI located at the California Institute of Technology.

  • HIRES Radial Velocity Processing Environment
    NExScI, in collaboration with Caltech and the Keck Observatory, is providing access to a processing environment suitable for producing precision radial velocities for HIRES data that have been acquired in a specific manner. The processing environment runs on servers at NExScI and is accessible through python web services calls, which the user runs on their own client-side machines. The precision radial velocity code is not available to download and is otherwise not visible to the users. To use this service, a user must have PI HIRES data in the Keck Observatory Archive (KOA) that were taken in the proper configuration and a user must install a small python package on their location machine. The python package is utilized to log on to the service, download data from the archive to the server-side processing environment, invoke the reduction and processing of the data, and extract the precision radial velocity results.

  • 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.
