Best-fit orbital solutions for HD 196885. Top row: radial velocity solution and phase folded model curves, with CORAVEL, CORALIE98, CORALIE07, and CORALIE14 measurements shown in orange, blue, green, and purple, respectively. Bottom row: observed and fitted proper motions in right ascension and declination. The thick black line is the best-fit orbit obtained by the simultaneous fit of radial velocities and proper motion anomalies, with 50 orbits randomly drawn from the posterior distributions and color-coded according to the mass of the outer massive companion, and the proper motion measurements from HIPPARCOS and Gaia EDR3 are shown in orange. Note: in the radial velocity phase folded plot for HD 196885 b, the low-precision CORAVEL data are not shown in order to better display the radial velocity curve of the low-amplitude inner companion.
