摘要
我们描述暗能量巡天（DES）的首次公开数据发布 DES DR1，包含在前三年 DES 科学运行中组装的归约单历元图像、叠加图像、叠加源星表以及关联产品和服。DES DR1 基于 2013 年 8 月至 2016 年 2 月由安装在智利托洛洛山美洲际天文台 4 米 Blanco 望远镜上的暗能量相机在 345 个不同夜晚获取的光学/近红外成像。我们发布来自 DES 广域巡天的数据，覆盖南银帽约 5,000 平方度天区，采用 grizY 五个宽波段测光。DES DR1 的中值交付点扩散函数为 g = 1.12、r = 0.96、i = 0.88、z = 0.84、Y = 0.90 角秒 FWHM，所有波段测光精度 < 1%，天体测量精度为 151 mas。在 S/N = 10 下直径 1.95" 孔径的中值叠加星表深度为 g = 24.33、r = 24.08、i = 23.44、z = 22.69、Y = 21.44 星等。DES DR1 包含由约 39,000 次单独曝光生成的约 10,000 个大小为 0.534 平方度的叠加图中探测到的近 4 亿个不同天体。经过基本天体质量筛选的基准星系与恒星样本分别包含约 3.10 亿和约 0.80 亿个对象。这些数据可通过一系列接口访问，包括查询 Web 客户端、图像截切服务器、jupyter notebooks 以及交互式叠加图像可视化工具。DES DR1 是迄今在所获深度与测光精度下最大的测光数据集。
