摘要
Gaia-ESO 公共光谱巡天是一项雄心勃勃的项目，旨在获取 100,000 颗恒星的天体物理参数与元素丰度，包括银河系恒星族的大代表性样本，以及定义明确的 60 个（外加 20 个档案）疏散星团样本。我们提供基于基准恒星和星团校准的内部一致结果，覆盖极宽的丰度与年龄范围。这提供了一套具有内在价值的遗留数据集，同样也是用于其他及未来恒星巡天与 Gaia 天体物理参数同质化的大范围数据集。本文概述了巡天方法学、科学目标与实施，包括对 GIRAFFE 光谱数据处理的说明。 companion 论文（arXiv:2206.02901）介绍了巡天结果。Gaia-ESO 力求量化测量不确定度中的随机与系统贡献。因此利用了所有可用的光谱分析技术，每条光谱至多由若干不同分析流水线分析，并投入大量努力对所得参数进行同质化与校准。我们在此描述了直至向 ESO 科学档案设施交付处理后数据产品的一系列活动。Gaia-ESO 巡天在 2011 年 12 月至 2018 年 1 月间利用分配到的 340 个 VLT 夜，通过 GIRAFFE 与 UVES 获取了 115,000 颗恒星的 202,000 条光谱。完整一致归约的最终光谱数据集于 2020 年末通过 ESO 科学档案设施发布，完整的天体物理参数集随后于 2022 年发布。
