Open Data/Open Source: Seismic Unix scripts to process a 2D land line

key datasets produced

This processing sequence produces many datasets, but the best files for additional processing are:

1. allshots.su - unprocessed field data with geometry in headers. Bad traces and aux traces removed.
2. velfiltcdpsmuterstat - preprocessed cdp gathers with residual static applied ready for normal moveout.
3. vpickorig.txt - final stacking velocities.
4. rstack1.su - final residual statics stack.
5. mig.su - post stack kirchhoff migrated data.
