VVV tiles b248 and b333 proper motions

We use near-infrared, ground-based data from the VISTA Variables in the Via Lactea (VVV) survey to indirectly extend the astrometry provided by the Gaia catalog to objects in...本研究采用银道面近红外变源巡天（VISTA Variables in the Via Lactea, VVV）获取的近红外（near-infrared）地面观测数据，将盖亚星表（Gaia catalog）所提供的天体测量（astrometry）数据间接拓展至……中的天体。
