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

Second Pass Residual Statics

The command:

scons rstack1.view

or

./rstack1.job

creates a stack with second pass residuals shown in Figure 13. I compared figures 11 and 13 and did not see any improvement.

A zoom plot can be produced with the command:

scons zoomrstack1.view

or

./zoomrstack1.job

I enjoyed comparing the zoom plots of the initial brute stack and the stack with two iterations of residual statics and velocity analysis. These plots are not included in the paper, but you can create them with the commands:

scons zoombrutestack.view & 
scons zoomrstack1.view &

or

./zoombrutestack.job & 
./zoomrstack1.job &

Make the plots full screen size and toggle between the windows using the buttons on the bottom run bar. The event disruptions that line up vertically are static problems solved by the residual statics process.
