Correlation of observed rotational splittings and mode-trapping parameters with the reference model mode-trapping parameters. Upper panel: Mode-trapping parameter, ζ_obs, of the synthetic star as a function of the mode-trapping parameter, ζ, of the potential reference model. The black, dashed line is a fit to the data to illustrate the linear relation. Lower panel: Rotational splittings, δω_obs, of the synthetic star as a function of the mode-trapping parameter, ζ, of the potential reference model.
