Notes. The profile type used to compute the synthetic rotational splittings is given in the first column. Core and envelope rotation rates were calculated with target radii of r0/R = 0.003 and r0/R = 0.98, respectively. When varying the core-to-envelope ratio the envelope rotation rate was set to 50 or a 100 nHz. The eMOLA results are taken from Ahlborn et al. (2022) (their Table 1).
