NEID Archive

The basic form enables searching the archive based on the following fields:
  • Observation date (UTC): a calendar widget provides shortcuts to useful date ranges, or custom date ranges may be entered in mm/dd/yyyy format
  • Program ID: NOAO proposal/program ID (e.g. 2019B-2222)
  • PI last name: Last name of the principal investigator. Partial and lowercase names are allowed.
  • Coordinates or Object name: See for allowed catalogues and formatting for object names. Coordinates may be entered in either sexagesimal or decimal degrees (J2000). All data containing objects within 30 arcseconds of the input coordinates are returned. Click the icon next to the search box for examples.

The results of the search are displayed in an interactive table below the search form. Columns may be sorted, filtered, or hidden using the icons at the top of the table. Hover over the filter box to see the options for column filtering.

Proposal IDs are added to the database before any data is collected. Querying by proposal ID will return an empty result until your observations begin to be executed and are processed by the pipeline.

Individual files may be downloaded by clicking on the file name, or all currently visible files may be downloaded via a wget script by clicking the "Create script to download files" button.

All Level0 metadata is public and visible to all users.


The columns returned by the Search form are:
  • filename: name of the Engineering, Level0, Level1, or Level2 FITS file. For Level0, all metadata, including the filename, is public, but you will only see a link to file if you have permission to access that program or the data is public.
  • object: custom object name entered by the PI (includes a link to SIMBAD if the SIMBAD ID exists)
  • qobject: object name used for the barycentric corrections
  • qra: RA in sexagesimal
  • qdec: Dec in sexagesimal
  • obsdate: date of observation in YYYY-MM-DD HH:MM:SS
  • exptime: exposure time in seconds
  • obsmode: observing mode (hr = high resolution, he = high efficiency)
  • obstype: obervation type (Cal = Calibration, Sci = Science, Eng = Engineering)
  • program: NOAO proposal ID
  • piname: PI name
  • airmass (L1 and L2 only): airmass
  • seeing (L1 and L2 only): seeing in arcsec
  • moonagl (L1 and L2 only): target-moon angle in degrees
  • swversion (L1 and L2 only): pipeline version used to process the data
  • ccfjdsum (L2 only): Barycentric Julian Day (BJD)
  • ccfrvmod (L2 only): RV value in km/s
  • dvrms (L2 only): error in RV value



The PI must send an e-mail to to request that access be given to other collaborators. Please include first names, last names, e-mail addresses, and the programs that the collaborators should be granted access to. The sender must be the PI for all programs listed. Only the PI may make such requests.
