Detection limits on msini following Bonfils et al. (2013) for the RV residuals of PM J02489–1432E after subtracting out the most prominent 28.5 d signal (Sect. 6). Any planet above the blue line is excluded with 99.9% confidence. The orange line is the mass corresponding to a semi-amplitude of 3 m s⁻¹. TOI-1201 b is indicated by a dashed gray line. Planets with long-period values greater than the time baseline are marked with a gray shaded region.
