$^{a}$ Masses are given in the same order as for spectral types, 
where $f(m)$ indicates that the mass function is given. \\
$^{b}$ Orbital period. \\
$^{c}$ Rotation (photometric) period. \\
$^{d}$ Inclination of the pole of the orbital plane or of
the rotation axis. \\
$^{e}$ Data from Fekel (\cite{Fekel96}). \\
