Kernels for the sensitivity of sectoral Rossby waves to variations in rotation rate for azimuthal orders m = 1, 3, 6, 9, 12, and 15 (from left to right, top to bottom). The different panels show the kernels in the meridional plane and the kernels are symmetric about the equator. The vertical axis is the rotation axis. The spatial grid is in units of R_⊙, and the grided region denotes the convection zone.
