暗能量光谱巡天第一次数据释放(DESI DR1)
收藏资源简介:
DESI 第一次数据释放(DR1)涵盖了从 2021 年 5 月至 2022 年 6 月期间进行的主巡天观测,包含了超过 1,800 万个独特天体目标的光谱数据。该数据集不仅包括主巡天观测所获得的数据,还整合了DESI巡天验证所获取的所有相关数据。这些早期数据已通过与主巡天数据相同的数据处理管道进行了重新处理。 DESI DR1的总数据量超过 300TB,其中包含原始光谱数据、处理后的光谱数据、红移星表、大尺度结构星表、QSO 星表、目标源星表以及增值星表。当前版本提供红移星表、大尺度结构星表与QSO星表。
The first data release (DR1) of the Dark Energy Spectroscopic Instrument (DESI) covers the main survey observations conducted between May 2021 and June 2022, and contains spectroscopic data for over 18 million unique astronomical targets. This dataset not only includes data acquired from the main survey, but also incorporates all relevant data obtained during the DESI survey validation phase. These early data have been reprocessed using the same data processing pipeline as that used for the main survey data. The total data volume of DESI DR1 exceeds 300 terabytes (TB), which includes raw spectroscopic data, processed spectroscopic data, redshift catalogs, large-scale structure catalogs, quasar (QSO) catalogs, target source catalogs, and value-added catalogs. The current release provides redshift catalogs, large-scale structure catalogs, and QSO catalogs.
