Recovery test for the MCMC method using the model and dataset of star B. Left panel: Recovered rotation profiles as a function of normalised radius. The shaded area provides the 1σ uncertainties on the inferred profiles, and the target is plotted in light purple. Right panel: Rotation splittings as a function of frequency for the model of star B (circles indicate dipolar modes, and squares show quadrupolar modes), using the simulated profile illustrated in light purple in the left panel.
