摘要
大天区面积多目标光纤光谱望远镜（LAMOST）巡天是一项光谱巡天，最终将覆盖约半个天球并收集 1000 万条恒星、星系和 QSOs 的光谱。先导巡天和第一年常规巡天的天体均包含在 LAMOST 首次数据发布（DR1）中。先导巡天于 2011 年 10 月开始，2012 年 6 月结束，其数据已于 2012 年 8 月作为 LAMOST 先导数据发布向公众发布。常规巡天始于 2012 年 9 月，并于 2013 年 6 月完成首年运行。LAMOST DR1 共包含 1202 个曝光板，含 2,955,336 条光谱，其中 1,790,879 条光谱的观测信噪比 S/N >10。根据 LAMOST 数据政策，所有 S/N>2 的数据作为 LAMOST DR1 正式发布。本次数据发布共包含 2,204,696 条光谱，其中 1,944,329 条为恒星光谱，12,082 条为星系光谱，5,017 条为类星体。DR1 不仅包含光谱，还包含三个带测量参数的恒星星表：具有高质量光谱的 AFGK 型星（1,061,918 条）、A 型星（100,073 条）和 M 型星（121,522 条）。本文介绍了巡天设计、观测与仪器限制、数据归约与分析以及一些注意事项。还提供了光谱文件和参数星表的 FITS 结构描述。
