Allowed parameter space of semi-major axis a and eccentricity e of the relative orbit of GJ 676B around GJ 676A at 3σ: the area between solid lines corresponds to line-of-sight relative distances z<z₀, whereas the area between dashed lines is for z>z₀. Arrows show the directions of increasing z and the hatched and filled areas correspond to positions of GJ 676B in front and behind GJ 676A, respectively, with relative distance z exceeding z_Gaia = 2400 AU that can be resolved with Gaia parallaxes.
