Top: observed rotational splittings as a function of ν/Δν for the Kepler star KIC 5356201 (Beck et al. 2012). For this star, the mean large separation is Δν = 15.92 μHz while the mean g-mode spaging is ΔΠ = 86.11 s and the maximum rotational splittings is δν_max = 0.405 nHz. Bottom: rotational splittings normalized to δν_max are folded with (ν − ν₀)/Δν.
