Projection of HD 3167 in the plane of sky for the best-fit orbital architecture (the top and bottom panels show configurations A and B, respectively; see text). The stellar spin axis is displayed as a black arrow extending from the north pole. The stellar equator is represented as a black line. The stellar disk is colored as a function of its surface RV field. Normals to the orbital planes of HD 3167b and HD 3167c are shown as green and brown arrows, respectively. Thick solid curves with corresponding colors represent the best-fit orbital trajectories. The thin lines surrounding them show orbits obtained for orbital inclination, semi-major axis and sky-projected obliquity values drawn randomly within 1σ from their probability distributions. The star, the planets HD 3167b and HD 3167c (black disks), and their orbits are shown to scale. HD 3167d, which orbits in between HD 3167b and HD 3167c, is not shown because of its unknown inclination.
