Born Traveltime Sensitivity Kernels
 Web interface to calculate travel time sensitivity kernels. The linear sensitivity kernels are based on a single-scattering Born approximation. There are three possible calculations. The first set of calculations provides three-dimensional p-mode kernels for sound-speed perturbations, as described by Birch et al (2004). The second set of calculations provides three-dimensional travel-time sensitivity kernels for flows as described by Birch and Gizon (2007). The third set provides two-dimensional f-mode kernels for flows, as described by Jackiewicz et al. (2007).
