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