NEW! PI Access to LWS Data and Public Access to ESI Data Now Available: Data Access

Funded by NASA, the Keck Observatory Archive (KOA) is a joint development between the W. M. Keck Observatory (WMKO) located in Waimea, Hawaii and the NASA Exoplanet Science Institute (NExScI) located in Pasadena, California. Currently, KOA archives data taken with HIRES, NIRSPEC, NIRC2, LRIS, KI (Keck Interferometer), MOSFIRE, DEIMOS, ESI, OSIRIS, NIRC, and LWS.

The process by which data are archived is as follows:

  • Locate all FITS files taken in the previous 24 hour period
  • Determine the validity and data integrity of each file
  • Add meta-keywords to the FITS header
  • Archive the metadata (native + meta-keywords) for each FITS header
  • Archive the data for each FITS file
  • Archive ancillary data associated with each night's data
    Ancillary data include Keck nightly plots of weather and image quality trends and, when available, all-sky images and photometric data

The physical location of the archive is at NExScI. Both metadata and raw FITS files are transferred via the internet from WMKO to NExScI, and are available through a User Interface within hours of the end of observations. Both the data files and the metadata are subject to a proprietary period policy. During the proprietary period, program PIs will be able to access their data via a user login/password protected site. The data are released to the public upon expiration of the proprietary period.
