We compute f-mode travel-time sensitivity kernels for flows. Using a two-dimensional model, the scattered wavefleld is calculated in the first Born approximation. We test the correctness of the kernels by comparing an exact solution (constant flow), a solution linearized in the flow, and the total integral of the kernel. In practice, the linear approximation is acceptable for flows as large as about 400 m/s.
