January 22, 2025: The NEID Archive is experience a slowdown in download speeds. The systems team is working on the issue.

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.

News

  • January 29, 2025 2024B data processing is temporarily halted as wavelength solutions using the LFC are being optimized. We expect that 24B processing will restart by 07 February. 2024B data that have already been processed will be reprocessed on an expedited basis. Reprocessing of earlier science data with V1.4 of the DRP is still ongoing. Science data reprocessing should be complete by mid-February.
  • December 10, 2024 The Advanced Search page has been updated to allow selection of multiple processing versions of lev1 and lev2 data. In the pipeline version pulldown, select the versions you are interested in - multiple rows will be returned for the same lev0 data that has multiple pipeline reductions available. PyNEID and TAP users can access the metadata for the all versions of the reduced data by using adql queries to select from the neidl1_all and neidl2_all tables. The flagged column has been updated to show 0 (pass quality check) or 1 (fail quality check). The rejected column has been updated to show 0 (okay signal-to-noise) or 1 (low signal-to-noise.)
  • Beginning July 1, 2024 Due to etalon instrument servicing, LFC data will be taken instead of etalon data for the nighttime science observations from July 1-22, 2024 (UT July 2-23; until WIYN’s shutdown). RV values are expected to be unaffected. All solar data will be paused from July 1, 2024 until the etalon is back in service (anticipated mid December 2024.)
  • The current version of the NEID pipeline is v1.4.0 (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.
