NEID pipeline processing will be delayed due to system maintenance June 17 - 19th.

Modern extremely precise 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- March 14, 2025 All science data has been reprocessed with
v1.4 of the DRP. Please note that v1.4 data should not be
combined with previous processing versions as the wavelength and drift
solutions have significantly changed. Reprocessing of the solar data
is ongoing.
- 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,
February 5, 2025.
- The current version of the NEID pipeline is v1.4.2 (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.

files.
