Artificial Data for Local Helioseismology

We present artificial data generated with a new magneto-acoustic-gravity-wave (MAG-wave) algorithm we have developed and implemented for the purpose of testing theoretical approaches to local helioseismology. Wave fields are represented spectrally with Fourier series in the horizontal directions and with a B-spline representation in the vertical. Algorithm-accuracy and code-performance characteristics are presented, and new results for subsurface flows are discussed. This work is supported by NASA contract NNG06EA03C.
