Description

We present the second public data release of the Dark Energy Survey, DES DR2, based on optical/near-infrared imaging by the Dark Energy Camera mounted on the 4m Blanco telescope at Cerro Tololo Inter-American Observatory in Chile. DES DR2 consists of reduced single-epoch and coadded images, a source catalog derived from coadded images, and associated data products assembled from 6yr of DES science operations. This release includes data from the DES wide-area survey covering ~5000deg^2^ of the southern Galactic cap in five broad photometric bands, grizY. DES DR2 has a median delivered point-spread function FWHM of g=1.11", r=0.95", i=0.88", z=0.83", and Y=0.90", photometric uniformity with a standard deviation of <3mmag with respect to Gaia DR2 G band, a photometric accuracy of ~11mmag, and a median internal astrometric precision of ~27mas. The median coadded catalog depth for a 1farcs95 diameter aperture at signal-to-noise ratio =10 is g=24.7, r=24.4, i=23.8, z=23.1, and Y=21.7mag. DES DR2 includes ~691 million distinct astronomical objects detected in 10169 coadded image tiles of size 0.534deg^2^ produced from 76217 single-epoch images. After a basic quality selection, benchmark galaxy and stellar samples contain 543 million and 145 million objects, respectively.
