Software

Most of the software needed is already available at SEP. Besides elementary tools such as Fortran90 compilers, SEPlib, Matlab and Mathematica, the $\Delta$Image-$\Delta$Slowness operator is already included in the gendown (Biondo Biondi) and WEI (Paul Sava) packages, already in existence at SEP. An out-of-core optimization library (oclib) for inverting large 3D datasets has already been written Sava (2001).
