2D Pre-Stack Depth Migration
2008: Parallel (MPI) 2D pre-stack depth migration, 2D wavefield extrapolation, and 2D Greens function calculation. All programs make use of WLSQ optimised one-way wavefield extrapolation operators.

If you are compiling and running demo and example scripts of the 2D FD code and find any bugs or have suggestions for improvement. Please e-mail them to me, so I can update the code. Feedback is also highly appreciated and suggestions for improvements, or extra functionality are welcome.
If you find the code usefull in your research please mention this web-page in your references our refer to our paper: "Finite-difference modeling experiments for seismic interferometry" Thorbecke and Draganov, Geophysics, Vol. 76, no 6 (November-December); p H1--H18.
For data in and output the software makes use of segy headers (in SU style: without ebcdic and binary header and in local IEEE format (no XDR)). Parameter input for the programs is based on Seismic Unix (SU), every program contains a selfdoc, and the programs can be used in a SU environment. The programs are completely self-supporting and no additional packages or libraries have to be installed.
