Abstract (from CDS):

New data obtained with the 4.1 m Southern Astrophysical Research (SOAR) telescope at Cerro Pachon, Chile, allowed us to revise the orbits and system masses of the following southern visual double stars: WDS 01477-4358 (I 52), WDS 01500-0408 (A 2602), WDS 02514-2139 (DON 43), WDS 03189-0101 (BU 1177), WDS 04142-4608 (RST 2338), WDS 06274-2544 (B 114), WDS 18434-5546 (B 398), WDS 20002-5522 (B 459 BC), WDS 20081-3929 (RST 2134), WDS 22007-5002 (I 1450), and WDS 22504-1744 (DON 1038-BD-18 6201). In addition, the orbit of the WDS 15332-2429 Aa, Ab (CHR 232 Aa, Ab) system was calculated for the first time. When available, we used the Hipparcos parallax to check the accuracy of our calculations of individual masses. In some cases, the dynamical parallaxes directly obtained from the orbital elements may be more valid than the satellite data. As far as the lack of spectral data and parallax associated with the WDS 22504-1744 (DON 1038 or BD-18 6201) system is concerned, we were able to assign a spectral type using the orbital elements along with the dynamical parallax and photometric information available. Other orbital and physical properties of these stars are also discussed herein.
