yCat(2019)
摘要
We describe the first public data release of the Dark Energy Survey, DES DR1, consisting of reduced single-epoch images, co-added images, co-added source catalogs, and associated products and services assembled over the first 3yr of DES science operations. DES DR1 is based on optical/near-infrared imaging from 345 distinct nights (2013 August to 2016 February) by the Dark Energy Camera (DECam) mounted on the 4m Blanco telescope at the Cerro Tololo Inter-American Observatory in Chile. We release data from the DES wide-area survey covering~ 5000deg 2 of the southern Galactic cap in five broad photometric bands, grizY. DES DR1 has a median delivered point-spread function of g= 1.12, r= 0.96, i= 0.88, z= 0.84, and Y= 0.90" FWHM, a photometric precision of< 1% in all bands, and an astrometric precision of 151mas. The median co-added catalog depth for a 1.95" diameter aperture at signal-to …
