Gaia-PS1-SDSS (GPS1) proper motion catalog

We combine Gaia DR1, PS1, Sloan Digital Sky Survey (SDSS), and 2MASS astrometry to measure proper motions for 350 million sources across three-fourths of the sky down to a...本研究结合盖亚数据发布1（Gaia DR1）、PS1、斯隆数字巡天（Sloan Digital Sky Survey，SDSS）以及2微米全天巡天（2MASS）的天体测量数据，对覆盖四分之三全天区、亮度极限至……的3.5亿个天体源的自行进行了测量。
