This experiment will depend on pandas and numpy python libraries to interpolate the points in the interface.

The interpolate.py program generate a layers.asc file in the madagascar ascii format. This file will be read for sfdd to be converted in .rsf format

This SConstruct uses interpolate.py, numpy and pandas libraries to interpolate a set of points describing the interfaces, generate the model and do finite diferences modeling to obtain the shot gathers

Use kirchoff newton modeling using ray tracing with the SConstruct available in the Madagascar website. This method is easier than Finite Diferences and can improve computational number of tests and save time

The Finite Diferences modeling and the interpolation it needs in this SConstruct will spend to much time and computational resources. So it is better use ray tracing with sfunif2.

🎉 Feature request
Is your feature request related to a problem? Please describe.
Use the vfsa programs to get the CRS parameters (RN, RNIP and BETA) in a two interface model with constant velocity layers for both reflector surfaces.
Describe the solution you'd like
Modeling should use a finite difference algorithm in order to build the seismic data cube. After that, repeat the same process in the usage example twice, one for each reflector. Do the same as in the usage example, show the CRS surfaces and error.
Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.
