abstract

  • Abstract 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 5 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.
