Best-fit Keplerian model parameters from fitting HD 12167’s ¹²CO velocity map.

Position angle (deg)	59.6 ± 0.01
Inclination (deg)	43.8 ± 0.02
Stellar mass (M_⊙)	1.89 ± 0.001
v_BARY (m s⁻¹)	7860 ± 1
RA offset (mas)	−3.1 ± 0.1
Dec offset (mas)	19.8 ± 0.1

Notes. The quoted best-fit values are the median of the marginalised distribution. The uncertainties are based on the 16th and 84th percentiles of the marginalised distributions. We note that these uncertainties are likely underestimated.
