Frequently, the full inverse problems that one would like to solve prove intractable because of computational constraints. Due to the enormous seismic data sets that already exist and those forthcoming, this is a problem that needs to be addressed. To this end, we present a very efficient linear inversion algorithm for local helioseismology. It is based on a subtractive optimally localized averaging (SOLA) scheme in the Fourier doma","authors_text":"1), 2), (2) New Mexico State University, (3) Colorado Research Associates Division, (4) Institut fuer Astrophysik, 5), (5) Department of Geosciences, (6) Institut fuer Numerische und Angewandte Mathematik, (7) Universite de Toulouse, A.C.
