Scientific paper

The combined spectroscopic and interferometric orbit of the single-lined binary dwarf HD 161198=Gliese 692.1 is derived from the radial velocities measured with two correlation radial-velocity spectrometers, CORAVEL and RVM, and from speckle-interferometry in the near IR. The orbital period is 7.0 years, eccentricity e=0.936. Secondary mass is about 0.3 solar mass.
