Scientific paper

The Yale/San Juan Southern Proper Motion SPM4 Catalog is the culmination of a highly successful 47-year collaboration between the National University of San Juan (UNSJ) and the Yale Southern Observatory (YSO). The SPM4 Catalog contains absolute proper motions, celestial coordinates, blue and visual passband photometry for 103 million stars and galaxies between the south celestial pole and δ=-20°. The Catalog is roughly complete to V = 17.5 and the precision of its positions and absolute proper motions is approximately 30 to 150 mas and 2 to 10 mas yr^{-1}, respectively.
