我们介绍了DECam局部体积探索调查（DELVE）的第二次公开数据发布（DR 2）。DELVE DR 2将新的DECam观测与来自暗能量调查、DECam遗产调查和其他DECam社区计划的DECam档案数据相结合。DELVE DR 2由160，000次曝光组成，在四个宽带光学/近红外滤光片（g，r，i，z）中覆盖了> 21，000 deg 2的高银河纬度（B角> 10°）天空。DELVE DR 2为125亿个天文源提供点源和自动孔径测光，其中值5σ点源深度为g = 24.3，r = 23.9，i = 23.5，z = 22.8等。所有四个滤光片都成像了17，000 deg 2的区域，为16.18亿个天文源提供了四波段测光测量。DELVE DR 2覆盖的面积是之前DELVE数据发布的4倍多，包含的天体数量大约是之前的5倍。DELVE DR 2通过NOIRLab Astro数据实验室科学平台公开提供。
We present the second public data release (DR2) from the DECam Local Volume Exploration survey (DELVE). DELVE DR2 combines new DECam observations with archival DECam data from the Dark Energy Survey, the DECam Legacy Survey, and other DECam community programs. DELVE DR2 consists of ∼160,000 exposures that cover >21,000 deg2 of the high-Galactic-latitude (∣b∣ > 10°) sky in four broadband optical/near-infrared filters (g, r, i, z). DELVE DR2 provides point-source and automatic aperture photometry for ∼2.5 billion astronomical sources with a median 5σ point-source depth of g = 24.3, r = 23.9, i = 23.5, and z = 22.8 mag. A region of ∼17,000 deg2 has been imaged in all four filters, providing four-band photometric measurements for ∼618 million astronomical sources. DELVE DR2 covers more than 4 times the area of the previous DELVE data release and contains roughly 5 times as many astronomical objects. DELVE DR2 is publicly available via the NOIRLab Astro Data Lab science platform.
