  Completion of the SUPERBLINK proper motion survey in the southern celestial
hemisphere has turned up 170 new stars with proper motion 0.45 arcsec/yr < pm <
2.0 arcsec/yr. 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 degrees < Decl. <0 degrees, and in low galactic
latitude areas south of Decl.= -30 degrees which had not been covered in
earlier data releases. Astrometric and photometric data are provided for the
170 new stars, along with finder charts. Most of the new discoveries are found
in densely populated fields along the Milky Way, towards the Galactic
bulge/center. The list of new discoveries includes 4 stars with proper motion
pm >1.0 arcsec/yr. 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 arcsec/yr < pm <2.0 arcsec/yr.
