STRong Lensing Insights into the Dark Energy Survey（STRDES）合作的主要目标是测量暗能量状态方程参数和暗物质的自由流长度。为了实现这一目标，科学家们正在暗能量巡天的成像数据中发现强透镜类星体，并跟踪它们以测量时间延迟、高分辨率成像和足以构建精确透镜模型的光谱学。在本文中，我们首先提出了预测的CODEDES。然后，我们描述了CFDES分类方案，并概述了2016年秋季的后续活动。我们继续详细介绍两种选择方法，离群值选择技术和形态学算法的结果，并提出一个系统，这可能是一个透镜类星体在一个不寻常的配置透镜模型。我们以2016年秋季活动的汇总统计数据结束。包括在配套论文中提出的检索（Anguita等人; Ostrovski等人），天文学家追踪了117个目标，确定了7个新的强透镜系统和7个几乎相同的类星体（NIQ），这些类星体可以通过对透镜星系的探测来证实。76名候选人被拒绝，27名候选人仍然没有结果，成功率在6- 35%之间。这一速度与之前的搜索（如SQLS）相当，尽管RISTODES的父数据集纯粹是光度学的，我们对候选数据集的选择不能依赖于光谱信息。
英文摘要：
The primary goals of the STRong lensing Insights into the Dark Energy Survey (STRIDES) collaboration are to measure the dark energy equation of state parameter and the free streaming length of dark matter. To this aim, STRIDES is discovering strongly lensed quasars in the imaging data of the Dark Energy Survey and following them up to measure time delays, high resolution imaging, and spectroscopy sufficient to construct accurate lens models. In this paper, we first present forecasts for STRIDES. Then, we describe the STRIDES classification scheme, and give an overview of the Fall 2016 follow-up campaign. We continue by detailing the results of two selection methods, the Outlier Selection Technique and a morphological algorithm, and presenting lens models of a system, which could possibly be a lensed quasar in an unusual configuration. We conclude with the summary statistics of the Fall 2016 campaign. Including searches presented in companion papers (Anguita et al.; Ostrovski et al.), STRIDES followed up 117 targets identifying 7 new strongly lensed systems, and 7 nearly identical quasars (NIQs), which could be confirmed as lenses by the detection of the lens galaxy. 76 candidates were rejected and 27 remain otherwise inconclusive, for a success rate in the range 6-35\%. This rate is comparable to that of previous searches like SQLS even though the parent dataset of STRIDES is purely photometric and our selection of candidates cannot rely on spectroscopic information.
