Abstract
The spectroscopic orbits of single-lined binary dwarfs HD 23439B, HD 2 37287 and HD 217580 are derived from the radial velocities measured wi th two correlation radial-velocity spectrometers, CORAVEL and RVM. The mutual agreement of these two data sets is analyzed and found to be q uite good. The estimated minimum mass of secondary component correspon ds to that of M-type dwarf for the first 2 systems and is equal to 0.0 6 solar mass for HD 217580.
