Notes. First column shows the dispersion ratio for the nominal case with typical observed uncertainties on the rotational splittings and range of modes. The second and third columns have the observed uncertainty in the splittings reduced by factors of 10 and 100. The fourth and fifth column have the number of modes increased and decreased, respectively, by changing the range of the radial orders, which changes the uncertainty. The last column shows the dispersion ratio for inversions including = 1,2,3 modes, subsequently the uncertainty is also reduced. The trade-off parameter is always μ = 107.
