Radial integrands for computing the frequency shift of a p mode with lp = 2, mp = 0, np = 20 caused by a g mode with lg = 2, mg = 0, ng = −36. When integrating over radius, the total integrand yields the total frequency shift δνp (both panels). The contributions to the total integrand resulting from the structural changes and the flow are also shown (right panel). The spike at the surface boundary is due to numerical difficulties in computing second order derivatives at the boundary. Therefore, the three outermost radial grid points were discarded.
