本文报告了WEAVE LIFU两个西班牙TAC项目的初步成果，包括对含OB型星星团的高分辨率多历元光谱观测和低分辨率普查，并介绍了数据处理工具UNWIND，以表征星团中OB星族群及其多重性。
AI 中文摘要
我们展示了两个西班牙TAC项目使用WEAVE LIFU获得的初步结果，这些数据自2023年10月起持续获取。第一个项目对九个星团进行高分辨率多历元光谱观测，这些星团在WEAVE LIFU的视场内包含至少3颗O型星（以及更多B型星），并且从拉帕尔马可观测，目的是研究OB型星的光谱多重性。第二个项目尽可能多地获取包含OB型星的星团的单次低分辨率光谱，目的是表征那些因过于拥挤而无法用保障时间SCIP项目适当研究的区域中的OB型星族群。该项目已在广泛的环境（从H II区到无气体星团）和距离（从太阳邻域内的星团到（邻近的）河外星系系统）中观测了54个星团。我们还介绍了为该程序开发的工具，包括数据立方体处理和可视化工具，以及UNWIND——一种拟合并扣除观测光谱中星际介质特征的代码。
英文摘要
We present the first results of two Spanish TAC programs using the WEAVE LIFU that have been obtaining data since October 2023. The first one is obtaining high-resolution multi-epoch spectroscopy of the nine stellar clusters that contain a minimum number of 3 O-type stars (and many more B stars) within the field of view of the WEAVE LIFU and that are accessible from La Palma with the purpose of studying the spectroscopic multiplicity of the OB stars. The second program is obtaining single-shot low-resolution spectroscopy of as many stellar clusters with OB stars as possible with the purpose of characterizing the OB-star population in those regions that are too crowded to be properly studied with the guaranteed time SCIP program. That program has already observed 54 clusters in a wide range of environments, from H II regions to gas-free clusters, and distances, from clusters in the solar neighbourhood to (nearby) extragalactic systems. We also present the tools developed for this program, which include a data cube processing and visualisation utility and UNWIND, a code that fits and subtracts the ISM signature in the observed spectra.
