我们展示了来自大天区多目标光纤光谱望远镜试点调查的 58,360 M 矮星的光谱目录。对于目录中的每个光谱，都提供了光谱亚型、径向速度、Hα 等效宽度、许多突出的分子带指数和金属敏感参数 z。我们使用斯隆数字巡天数据第 7 版光谱 M 矮星目录来验证我们的光谱类型分类和径向速度测量方法的精度。 M 矮星的磁活动特性也可以通过 Hα 发射线来追踪。该目录中包含的分子能带指数对温度或金属丰度敏感，可用于进一步研究M矮星的物理性质。该 M 矮星目录可在网站 http://sciwiki.lamost.org/MCatalogPilot/ 上找到。
We present a spectroscopic catalog of 58,360 M dwarfs from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope pilot survey. For each spectrum in the catalog, spectral subtype, radial velocity, Hα equivalent width, a number of prominent molecular band indices, and the metal-sensitive parameter ζ are provided. We use the Sloan Digital Sky Survey Data Release 7 Spectroscopic M dwarf catalog to verify the precision of our methods of classifying the spectral types and measuring the radial velocities. The magnetic activity properties of M dwarfs are also traced by Hα emission lines. The molecular band indices included in this catalog are sensitive to temperature or metallicity, and can be used for further study of the physical properties of M dwarfs. This M dwarf catalog is available on the Web site http://sciwiki.lamost.org/MCatalogPilot/.
