摘要
Euclid 快速数据发布 Q1 包含面向名义宽幅调查深度的 63.1 平方度的 Euclid 深度场 (EDFs)。它涵盖了可见光和近红外空间成像及光谱数据、以及 u、g、r、i 和 z 波段的地面光度测量数据，以及相应的掩模。总体而言，Q1 包含约 3000 万个目标，分布在靠近黄道极的三个区域——EDFs-北、EDFs-南以及来自猎户座同一星座中的 EDF-Fornax 区域。本次数据发布——及其关联技术论文——的目的是两方面：首先旨在向社区传达 Euclid 调查数据的巨大潜力，描述数据内容，并帮助准备对即将发布的首次重大数据发布 DR1 的期望；其次可为利用 Q1 数据开展广泛的初始科学项目提供可能，涵盖从早期宇宙到太阳系。Q1 数据采用了早期版本的处理管线进行处理，管线已显示出良好性能，相较于发射前的开发相比实现了诸多改进。本文描述了 Q1 中公布的天区、观测、Euclid 及关联外部数据的顶层数据处理概览、Q1 光度掩模以及数据获取方式。我们还概述了由 Euclid 联盟科学家利用 Q1 数据集获得的初始科学结果，并对使用该数据时需注意的重要限制作出总结。作为补充产品，Q1 还包含对猎户云 Lynd 的暗云 1641 中星形成区域的观测，旨在技术目的进行 Euclid 性能验证阶段的观测。这一目标类型在 Euclid 的名义天区调查中较为罕见。
