摘要
我们公开 ALMA 中心分子区探索调查（ACES）大型项目中中等宽度光谱窗的数据，涵盖 SiO(2-1)、SO(2_2-1_1)、H13CO+(1-0)、H13CN(1-0)、HN13C(1-0) 和 HC15N (1-0) 等分子线过渡，角分辨率约为 2 弧秒，速度分辨率为 1.7 km/s。两个光谱窗的完整立方体以及关键数据产品将向社区开放。我们还呈现了六条线的集成亮度、峰值亮度、质心速度和 Galactic 经度-速度图。我们简要讨论了连续光谱与分子线发射之间的形态相关性，以及同配或同仍作物线对之间的亮度比。我们强调数据中值得关注的特征和趋势，这些特征将在即将发表的后续 ACES 科学论文中进行跟踪研究。
