The Gaia + PanSTARRS1 (PS1) + Sloan Digital Sky Survey (SDSS) + Two Micron All-Sky Survey (2MASS) (GPS1) catalog was released in 2017. It delivered precise proper motions for around 350 million sources down to a magnitude of ##IMG## [http://ej.iop.org/images/0067-0049/248/2/28/apjsab8d27ieqn1.gif] {$r\sim 20$} mag. In this study, we present GPS1+, the extension GPS1 catalog down to ##IMG## [http://ej.iop.org/images/0067-0049/248/2/28/apjsab8d27ieqn2.gif] {$r\sim 22.5$} mag, based on Gaia data release 2 (DR2), PS1, SDSS, and 2MASS astrometry. GPS1+ totally provides proper motions for ~400 million sources with a characteristic systematic error of less than 0.1 mas yr −1 . This catalog is divided into two subsamples, i.e., the primary and secondary parts. The primary ~264 million sources have either or both Gaia and SDSS astrometry, with a typical precision of 2.0–5.0 mas yr −1 . In this part, ~160 million sources have ...

扩展的Gaia–PS1–SDSS（GPS1 +）正确运动目录

盖亚+ PanSTARRS1（PS1）+斯隆数字天空测量（SDSS）+两微米全天空测量（2MASS）（GPS1）目录于2017年发布。它为大约3.5亿个信号源提供了精确的正确运动，其幅度最大为＃ ＃IMG ## [http://ej.iop.org/images/0067-0049/248/2/28/apjsab8d27ieqn1.gif] {$ r \ sim 20 $} mag。在这项研究中，我们展示了GPS1 +，即GPS1扩展目录，直至## IMG ## [http://ej.iop.org/images/0067-0049/248/2/28/apjsab8d27ieqn2.gif] {$ r \ sim 22.5 $} mag，基于Gaia数据版本2（DR2），PS1，SDSS和2MASS占星术。GPS1 +总共为约4亿个源提供了适当的运动，其系统误差小于0.1 mas yr -1。该目录分为两个子样本，即主要部分和次要部分。约有2.64亿个主要来源同时具有Gaia和SDSS占星术，的典型精度为2.0–5.0 mas yr -1。在这部分中，约有1.6亿个来源...
