MMT快照数据集是从MMT数据库中提取的特定时间点的快照。它包含了对象信息和轨道测量数据。对象信息记录了对象的MMT标识符、Norad标识符、名称、来源国家以及对象的变异性（非变化、非周期性、周期性）。轨道测量数据包括观测记录的标识符、Norad标识符、旋转周期、观测时间戳、名称、变异性、观测时间列表、标准化星等列表、相位角列表、距离列表和使用的过滤器列表。

MMT Snapshot dataset is a snapshot extracted from the MMT database at a specific point in time. It contains object information and track measurement data. Object information records the objects MMT identifier, Norad identifier, name, country of origin, and the objects variability (non-variable, aperiodic, periodic). Track measurement data include the record identifier, Norad identifier, rotational period, observation timestamp, name, variability, list of observation times, list of standardized magnitudes, list of phase angles, list of measured altitudes, and list of filters used.
