Abstract:
Completion of the SUPERBLINK proper motion survey in the southern
celestial hemisphere has turned up 170 new stars with proper motion
0.45"/yr<mu<2.0"/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 11600deg-2 in the declination (DE) range
-30°<DE<0° and in low Galactic latitude areas south of
DE=-30° 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, toward the Galactic
bulge/center. The list of new discoveries includes four stars with
proper motion mu>1.0"/yr. The total list of high proper motion stars
recovered by SUPERBLINK in the southern sky now includes 2228 stars
with proper motions 0.45"/yr<mu<2.0"/yr.
Description:
HPM stars were identified from data mining of the DSSs using the
SUPERBLINK software. The method has been described in much detail in
Papers I-III of this series (Lepine et al. 2002, Cat. J/AJ/124/1190,
2003AJ....126..921L 2003AJ....126..921L; Lepine 2005, Cat J/AJ/130/1247) and the accuracy
and completeness of the technique, for the northern sky survey, have
been documented in Lepine & Shara (2005AJ....129.1483L 2005AJ....129.1483L, Cat. I/298).
