\caption{Various orbital solutions for \usg\ derived with the FOTEL~program.
All epochs are in HJD-2~400~000 and the rms~error is error per 1~observation
of unit weight. Systemic velocities of individual spectrographs are
identified by the running numbers corresponding to those
from Table~\ref{jourv}. Rather large differences in the individual systemic
velocities probably do not reflect real changes but rather compensate
for the differences in line identifications and various subsets of lines
used by various authors to derive the published RVs.}
