Part of the Astronomy Datasets collection on Hugging Face.
Spectroscopic redshifts from the Dark Energy Spectroscopic Instrument
(DESI) Data Release 1 — the largest spectroscopic survey ever conducted.
This dataset contains the Bright Galaxy Survey (BGS) subset: 5,000,000 sources
with reliable redshift measurements (zwarn=0, main_primary=true).
DESI is a robotic fiber-fed spectrograph on the Mayall 4-meter… See the full description on the dataset page:
