Rotational splittings δν_n,l as a function of the mode inertia ratio ζ for KIC 11968334. The blue open circles represent the observed splittings plotted against the asymptotic ζ_as (derived from the period spacing ΔP), while the red triangles show the same splittings plotted against the model-predicted ﹩{\zeta }_{{\rm{mod}}}﹩ (derived from our best-fit MESA model). The solid red line and dashed blue line indicate the weighted linear fits for the model and asymptotic values, respectively. The resulting core rotation rates (﹩{{\rm{\Omega }}}_{{\rm{core}}}﹩) are listed in the legend, showing excellent agreement between the two methods.
