Astrometric accelerations in right ascension (μ_α cos δ) and declination (μ_δ) for HD 118203. The points near epochs 1991.25 and 2015.8 come from HIPPARCOS and Gaia EDR3, respectively. The best-fitting model is sketched with the black line. The model uncertainties are illustrated with 100 solutions drawn from the posterior distributions. Their colours code the orbital inclination of HD 118203 c, scaled at the right. The figure was plotted with ORVARA.
