NEID Archive

Search the 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 NASA Exoplanet Science Institute (NExScI) located at the California Institute of Technology.

Solar data from NEID is served by the Solar Radial Velocity Archive.


  • April 15, 2024 The object search has been updated to include an optional radius for spatial searches. For example when searching for Barnard's Star, enter 162 arcsec in the the radius field. This feature is helpful in finding sources that have very different astrometry between Gaia DR2 and the current version of Gaia (now DR3). If the radius field is left blank, the default spatial search radius is 30 arcsec.
  • The current version of the NEID pipeline is v1.3.0 (see NEID DRP docs and changelog) Data in the archive are currently being reprocessed with this latest version starting with the most recent data in the archive.
  • Use the Advanced Search page if you wish to access rejected files.
WIYN nightly weather logs are available here or you can use the calendar below to select a date (format mm/dd/yyyy). The default date is last night's date. If you do a NEID Archive search, and click on a row in the results table, the observation date for that row/night will be entered into the calendar. Press the "Get Weather" button to see the weather log for that night.
