一句话总结

本文宣布了 Dark Energy Spectroscopic Instrument (DESI) 的 Data Release 1，并列出贡献作者及所在机构。

ABSTRACT

Data Release 1 (DR1) of the Dark Energy Spectroscopic Instrument (DESI) includes the first 13 months of the DESI main survey as well as a uniform reprocessing of the Survey Validation data previously released in the Early Data Release. The full dataset is available at https://data.desi.lbl.gov/doc/releases/dr1. The Zenodo tarball includes all the code and data used to generate the figures and tables in the companion paper describing DR1. See the README.md file for details about the formats of each file as well as a link to the paper.
