Comparison of cumulative SKs for the core rotation rate, Ω_core, as a function of radius for synthetic data. The results obtained with the eMOLA and the MOLA inversions are shown with blue and light blue lines, respectively. The dotted grey line indicates the base of the convective envelope. The black line shows the cumulative SK for the core rotation obtained with the LSA. The construction of the SKs by applying the LSA is described in Sect. 5.
