Table 3: Journal of radial velocity data. The columns give the spectrum number (as from the Asiago 1.82 m Echelle + CCD log book), the heliocentric JD, and the heliocentric radial velocities (in km s^-1) for both components. An asterisk marks the spectra with a too severe blending of the lines for a meaningful measurement of radial velocities of each component. The latter have not been used in modeling of the binaries.
