Comparison of data to model orbits from the PT-MCMC posterior pdf. Left: RV data versus model comparison for HIP 36985AB. FEROS data points are plotted as red squares, CARMENES data points are plotted as green circles, and HARPS data points are plotted as cyan triangles. The best fit orbit to the direct imaging data, RV data, and both the HIPPARCOS and Gaia proper motion anomalies is plotted as a solid black line; blue lines depict 100 random orbits taken from the final converged PT-MCMC posterior pdf. Right: direct imaging data versus model comparison for HIP 36985AB. NaCo data points are plotted as orange circles, and SPHERE data points are plotted as lavender triangles. The best fit orbit to the direct imaging data, RV data, and both the HIPPARCOS and Gaia proper motion anomalies is plotted as asolid black line; blue lines depict 100 random orbits taken from the final converged PT-MCMC posterior pdf. The position of the primary is depicted with a black star symbol.
