New High Proper Motion Stars from the Digitized Sky Survey. Iv. Completion of the Southern Survey and 170 Additional Stars with Μ > 0.45′′yr−1.1

Completion of the SUPERBLINK proper motion survey in the southern celestial hemisphere has turned up 170 new stars with proper motion 0.45′′yr−1 < μ < 2.0′′yr−1. This fourth and final installment completes the all-sky, data-mining of the Digitized Sky Surveys for stars with large proper motions. The areas investigated in this final installment comprise 11,600 square degrees in the declination range −30 1.0′′yr−1. The total list of high proper motion stars recovered by SUPERBLINK in the southern sky now includes 2,228 stars with proper motions 0.45′′yr−1 < μ< 2.0′′yr−1.
