The program receives a seismic data cube organized in the following coordinates: n1 is the time, n2 is the offset, n3 is the CMP. The output of the program is the parameters cube organized in n1 is the 8 parameters and n2 is the parameters index in for each t0, m0 pair in the order and sampling determined by om0, dm0, nm0 and ot0, dt0, nt0 parameters passed through command line.

The v0 parameter is the near surface velocity of the model (used in CRS method) and input parameters temp0 (VFSA initial temperature) and C0 (VFSA damping factor) are control parameters to tune the VFSA algorithm for specific problems chosen arbitrarily.
