暗能量巡天 (DES) 是一项正在进行的光学巡天，旨在使用四种互补方法了解宇宙的加速膨胀：弱引力透镜、星系团计数、重子声振荡和 Ia 型超新星。为了进行 5000 平方度宽视场和 30 平方度超新星巡天，DES 合作组织建造了暗能量相机 (DECam)，这是一台 3 平方度、570 兆像素 CCD 相机，安装在托洛洛山美洲天文台 (CTIO) 布兰科 4 米望远镜的主焦点处。 DES 已经完成了名义上的五个观测季节中的第三个观测季节。本文介绍了 DES“第一年”（Y1）至“第三年”（Y3）、策略、调查作业程序概要、作业效率以及观测时间损失的原因。它提供了有关前三个季节数据质量的详细信息，并描述了我们如何针对厄尔尼诺南方涛动调整调查策略。
The Dark Energy Survey (DES) is an operating optical survey aimed at understanding the accelerating expansion of the universe using four complementary methods: weak gravitational lensing, galaxy cluster counts, baryon acoustic oscillations, and Type Ia supernovae. To perform the 5000 sq-degree wide field and 30 sq-degree supernova surveys, the DES Collaboration built the Dark Energy Camera (DECam), a 3 square-degree, 570-Megapixel CCD camera that was installed at the prime focus of the Blanco 4-meter telescope at the Cerro Tololo Inter-American Observatory (CTIO). DES has completed its third observing season out of a nominal five. This paper describes DES “Year 1” (Y1) to “Year 3” (Y3), the strategy, an outline of the survey operations procedures, the efficiency of operations and the causes of lost observing time. It provides details about the quality of the first three season's data, and describes how we are adjusting the survey strategy in the face of the El Niño Southern Oscillation.
