Contributed Datasets
Certain projects, scientists, or time-granting institutions have publicly released datasets relating to a specific target or set of targets. These “contributed datasets” are listed below. Some contributed datasets contain only the raw data; others include extracted spectra or images, or higher level products. Please see each Dataset page for details.
To submit contributed data to KOA, please contact the KOA Help Desk and refer to the Contributed Data Set Policy.
| Dataset | Description | Keck DEIMOS Archive of High Redshift Candidate Galaxies | This dataset provides uniformly reduced DEIMOS spectroscopy of 323 multislit masks targeting high-redshift galaxy candidates from the Keck Observatory Archive. It includes science-ready 1D and coadded 2D spectra with relative flux calibration and quality assessments. Contributed by PI Brad Holden. Release date: March 2, 2026 |
|---|---|
| The Keck/DEIMOS Stellar Archive | This dataset provides radial velocities and equivalent width measurements for individual stars in 78 Milky Way satellite galaxies and globular clusters as measured with DEIMOS and the 1200G grating. Contributed by PI Marla Geha. Release date: March 2, 2026 |
