    Abstract:
        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 ~5000deg2 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 0.534deg2 produced from
        76217 single-epoch images. After a basic quality selection, benchmark
        galaxy and stellar samples contain 543 million and 145 million
        objects, respectively.

    Description:
        To achieve the DES science goals, the DES Collaboration designed,
        built, and utilized the Dark Energy Camera (DECam), a 570 megapixel
        camera with a 3deg2 field of view installed at the prime focus of
        the 4m Blanco telescope at Cerro Tololo Inter-American Observatory
        (CTIO) in northern Chile.

        The first major release of processed DES data, DES DR1 (II/357),
        encompassed data products derived from the wide-area and the supernova
        surveys taken in the first three years of science operations
        (2013-August -- 2016-February).

        Here we present the content, validation, and data access services for
        the second public DES data release, DES DR2. DES DR2 comprises coadded
        images of size 0.534deg2 and source catalogs, as well as calibrated
        single-epoch CCD images, from the processing of all six years of DES
        wide-area survey observations and all five years of DES supernova
        survey observations. DES DR2 contains roughly 18TB of coadd images and
        3TB of tables. All DES DR1 data have been reprocessed as input into
        DES DR2.

        DES was scheduled to observe for 760 distinct full or half nights
        between 2013 August 15 and 2019 January 9. The DES DR2 coadd images
        and catalogs are derived from a subset of the wide-area component of
        DES and include exposures collected during 681 distinct nights.
        See Section 2.

        All magnitudes quoted in the text are in the AB system, and all
        astronomical coordinates are provided in the Gaia-CRF2 reference
        frame. All quoted uncertainties are 1{sigma} (roughly 68% confidence
        interval) unless indicated otherwise.

        1 = candidate stars
        2 = mostly galaxies
        3 = high-confidence galaxies
       -9 = no data
    Note (2): Magnitudes with errors >=99mag and errors >100mag have been set
