摘要
我们呈现CANDELS再电离时期Lyman-alpha发射（CLEAR）巡天的概览。CLEAR是一个130轨道的哈勃空间望远镜计划，使用宽场相机3（WFC3）IR G102光栅。CLEAR瞄准12个指向，分布于宇宙近红外深场河外遗产巡天（CANDELS）的GOODS-N与GOODS-S场。结合其他计划的现有光谱数据，完整CLEAR数据集包含这些场在0.8–1.7 μm的光谱成像。本文中，我们描述CLEAR巡天、巡天策略、数据获取、归约、处理及随本文发布的产品与星表。星表包含由测光与光栅光谱结合导出的6048个星系的发射线通量与红移，主要范围为0.2 < z < 3。我们也提供CLEAR科学目标与结果概览。连同本文，我们提供数据产品电子版本的链接，包括一维与二维提取光谱及发射线图。
