Left: best-fit orbital solution (thick line) and 50 draws from the posterior distribution (thin, coloured lines) for the Kepler-444 A-BC system, presented in the plane of the sky. Blue points indicate the observed relative astrometry of Kepler-444 BC, while open circles indicate predicted on-sky locations of the companion between 1980 and 2080. Right: same orbital solutions, presented in a top-down view. The observed astrometry is also deprojected into this view, using the inclination of the best-fit orbit. An arrow indicates the direction of this orbit. The colour bar indicates the total mass of the secondary component (i.e. M_B+M_C), and applies to both panels.
