PYNEID

Programmatic access to the tables of metadata and associated data products is provided via the PyNEID Python package. Documentation is available here.

DATA REDUCTION PIPELINE

Documentation for the NEID Data Reduction Pipeline is available here.

SOLAR SEARCH FORM

• Instrument
• Observation date (UTC): a calendar widget provides shortcuts to useful date ranges, or custom date ranges may be entered in mm/dd/yyyy format
• Data level: Select which level(s) you wish to search on (Engineering, Level 0, Level 1, Level 2, or All)

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.

To download an individual file, click on the file name. Click on the "Create script to download files" button to generate a script containing wget commands to download all the files you have access to. If you have filtered the results table, only the visible rows will be included in the download.

All Level 0 metadata are public and visible to all users.

COLUMN DESCRIPTIONS

• filename: name of the Engineering, Level 0, Level 1, or Level 2 FITS file. For Level 0, all metadata, including the filename, are public, but you will only see a link to the file if you have permission to access that program or the data are public.
• obsdate: date of observation in YYYY-MM-DD HH:MM:SS (UTC)
• 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
• sunagl (L1 and L2 only): elevation of the sun at the time of observation
• seeing (L1 and L2 only): seeing in arcsec
• swversion (L1 and L2 only): pipeline version used to process the data
• extsnr (L1 and L2 only): measured signal-to-noise (SNR) per pixel at the wavelength specified in the observation request. If no wavelength is specified then the SNR is calculated at 5530 Angstroms
• rejected (L1 and L2 only): flag indicating if file was rejected
• ccfjdsum (L2 only): Barycentric Julian Day (BJD)
• ccfrvmod (L2 only): RV value in km/s
• dvrms (L2 only): error in RV value
• flagged (L1 and L2 only); ('x' = flagged, blank = not flagged) Files did not pass quality control. Derived products may not be good for precision radial velocity work but may be useful for other science cases
