Modern extremely precisŧe radial velocity spectrographs are now being built with the capacity to feed light from the sun into the instrument in order to aid our understanding of the instrumental characteristics and the Doppler noise caused by convective motion on the surface of stars. The NASA-NSF Exoplanet Observational Research (NN-EXPLORE) program and the NASA Exoplanet Science Institute (NExScI) located at the California Institute of Technology are working together to provide the community access to the solar data products from as many instruments as possible. Reduced solar data products from the NEID spectrograph built by the Pennsylvania State University are currently available for download.

News

  • 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.
