TL;DR
This paper introduces a comprehensive all-sky star catalog with high proper motions, created through data mining of sky surveys, surpassing previous catalogs in completeness and coverage.
Contribution
It presents a new, nearly complete all-sky catalog of high proper motion stars, improving upon historic surveys with modern data mining techniques.
Findings
Catalog contains stars with proper motions >0.15"/yr
Achieves >98% completeness down to R=19 magnitude
Supersedes previous major proper motion catalogs
Abstract
A new all-sky catalog of stars with proper motions pm>0.15"/yr is presented. The catalog is largely a product of the SUPERBLINK survey, a data-mining initiative in which the entire Digitized Sky Surveys are searched for moving stellar sources. Findings from earlier proper motions surveys are also incorporated. The new all-sky catalog supersedes the great historic proper motion catalogs assembled by W. J. Luyten (LHS, NLTT), and provides a virtually complete (>98%) census of high proper motion stars down to magnitude R=19.
