SENSITIVITY KERNELS FOR HELIOSEISMIC TRAVEL TIMES IN SPHERICAL GEOMETRY-PRELIMINARY RESULTS

摘要

We discuss the problem of the computation of three-dimensional Frechet kernels in spherical geometry for use in time-distance helioseismology. In particular, we investigate the computation of the kernels that give the linear sensitivity of travel times to internal flows. Simple tests have been performed in the case of uniform rotation.
