Dark Energy Spectroscopic Instrument Data Release 1
Publish Time:2025-07-16
DESI Data Release 1 (DR1) includes spectra for more than 18 million unique targets from Main Survey observations taken between May 2021 and June 2022. In addition, DR1 includes all the data taken as part of DESI Survey Validation which was originally released as part of the Early Data Release but reprocessed with the same reduction pipeline as the Main Survey data. The DESI DR1 has a total data volume exceeding 300TB. It includes raw spectra, processed spectra, redshift catalogs, large-scale structure and QSO catalogs, target source catalogs, and value-added catalogs. Due to its massive size, only the redshift and large-scale structure/QSO catalogs are shared here.
