Convection affects the solar p-modes by additonally shifting the frequencies. This effect is small in comparison to the frequency splitting caused by the differential rotation. But, as the spatial resolution of the inversions for the differential rotation becomes better, it is important to know how these additional frequency shifts are blended into the splitting coefficients and how both might be disentangled. Therefore we carry out a numerical experiment. We calculate with quasi-degenerate perturbation theory the frequencies of p-modes that are affected by differential rotation and large-scale convection cells. This simulated data are inverted for differential rotation, and on that basis upper limits for the detectability of large-scale convection in global helioseismic data are derived.
