Description:
A large sample of visual multiples of spectral types F5-M has been
surveyed for the presence of spectroscopic sub-systems.
In table 1 we provide basic identifiers for the components or their
combinations, average radial velocities, parameters of correlation
dips and analysis of the velocity variability and physical relation.
Notes contain comments and additional identifiers. Individual radial
velocities yet unpublished are listed in table 2. Table 6 is extracted
from the Multiple Star Catalog (Cat. J/A+AS/124/75) for the analysis
of the statistics of spectroscopic+visual multiple stellar systems.

Note (1): If more than two unresolved visual components, '+' appears.
Note (2): If upper limits on Vsin(i) are given here instead of errors, this is
indicated by '*' in column 82.
Note (3): Variability status:
C: constant
C?: likely constant
V: variable
V?: likely variable
VO: variability likely due to visual orbital motion
S1O: single-lined binary with orbit

Asterisk indicates possible mixture of partially resolved components
affecting the velocity precision and equivalent width.
