Scientific paper

The spectroscopic orbits of single-lined binary dwarfs HD 23439B, HD 237287 and HD 217580 are derived from the radial velocities measured with two correlation radial-velocity spectrometers, correlation radial velocity (CORAVEL) and radial velocity meters (RVM). The mutual agreement of these two data sets is analyzed and found to be quite good. The estimated minimum mass of secondary component corresponds to that of M-type dwarf for the first 2 systems and is equal to 0.06 solar mass for HD 217580.
